50-165 3.56e-50

Immunoglobulin domain; The members here are composed of the immunoglobulin (Ig) domain found in the Ig superfamily. The Ig superfamily is a heterogenous group of proteins, built on a common fold comprised of a sandwich of two beta sheets. Members of this group are components of immunoglobulin, neuroglia, cell surface glycoproteins, including T-cell receptors, CD2, CD4, CD8, and membrane glycoproteins, including butyrophilin and chondroitin sulfate proteoglycan core protein. A predominant feature of most Ig domains is a disulfide bridge connecting the two beta-sheets with a tryptophan residue packed against the disulfide bond. Ig superfamily (IgSF) domains can be divided into 4 main classes based on their structures and sequences: the Variable (V), Constant 1 (C1), Constant 2 (C2), and Intermediate (I) sets. Typically, the V-set domains have A, B, E, and D strands in one sheet and A', G, F, C, C' and C" in the other. The structures in C1-set are smaller than those in the V-set; they have one beta sheet that is formed by strands A, B, E, and D and the other by strands G, F, C, and C'. Moreover, a C1-set Ig domain contains a short C' strand (three residues) and lacks A' and C" strand. Unlike other Ig domain sets, C2-set structures do not have a D strand. Like the V-set Ig domains, members of the I-set have a discontinuous A strand, but lack a C" strand.

163-267 5.94e-47

The link domain is a hyaluronan (HA)-binding domain. It functions to mediate adhesive interactions during inflammatory leukocyte homing and tumor metastasis. It is found in the CD44 receptor and in human TSG-6. TSG-6 is the protein product of the tumor necrosis factor-stimulated gene-6. TSG-6 has a strong anti-inflammatory effect in models of acute inflammation and autoimmune arthritis and plays an essential role in female fertility. This group also contains the link domains of the chondroitin sulfate proteoglycan core proteins (CSPG) including aggrecan, versican, neurocan, and brevican and the link domains of the vertebrate HAPLN (HA and proteoglycan binding link) protein family. In cartilage, aggrecan forms cartilage link protein stabilized aggregates with HA. These aggregates contribute to the tissue's load bearing properties. Aggregates in which other CSPGs substitute for aggregan might contribute to the structural integrity of many different tissues. Members of the vertebrate HPLN gene family are physically linked adjacent to CSPG genes. TSG-6 contains a single link module which supports high affinity binding with HA. The functional HA-binding domain of CD44 is an extended domain comprised of a link module flanked with N-and C- extensions. These extensions are essential for folding and functional activity. CSPGs are characterized by an N-terminal globular domain (G1 domain) containing two contiguous link modules (modules 1 and 2). Both link modules of the G1 domain of the CSPG aggrecan are involved in interaction with HA. Aggrecan in addition contains a second globular domain (G2) which contains link modules 3 and 4 which lack HA-binding activity. HAPLNs contain two contiguous link modules.

Link_domain_HAPLN_module_2; this link domain is found in the second link module of proteins similar to the vertebrate HAPLN (hyaluronan/HA and proteoglycan binding link) protein family which includes cartilage link protein. The link domain is a HA-binding domain. HAPLNs contain two contiguous link modules. Both link modules of cartilage link protein are involved in interaction with HA. In cartilage, a chondroitin sulfate proteoglycan core protein (CSPG) aggrecan forms cartilage link protein stabilized aggregates with HA. These aggregates contribute to the tissue's load bearing properties. Aggregates with other CSPGs substituting for aggregan may contribute to the structural integrity of many different tissues. Members of the vertebrate HAPLN gene family are physically linked adjacent to CSPG genes.

163-267 7.49e-28

The link domain is a hyaluronan (HA)-binding domain. It functions to mediate adhesive interactions during inflammatory leukocyte homing and tumor metastasis. It is found in the CD44 receptor and in human TSG-6. TSG-6 is the protein product of the tumor necrosis factor-stimulated gene-6. TSG-6 has a strong anti-inflammatory effect in models of acute inflammation and autoimmune arthritis and plays an essential role in female fertility. This group also contains the link domains of the chondroitin sulfate proteoglycan core proteins (CSPG) including aggrecan, versican, neurocan, and brevican and the link domains of the vertebrate HAPLN (HA and proteoglycan binding link) protein family. In cartilage, aggrecan forms cartilage link protein stabilized aggregates with HA. These aggregates contribute to the tissue's load bearing properties. Aggregates in which other CSPGs substitute for aggregan might contribute to the structural integrity of many different tissues. Members of the vertebrate HPLN gene family are physically linked adjacent to CSPG genes. TSG-6 contains a single link module which supports high affinity binding with HA. The functional HA-binding domain of CD44 is an extended domain comprised of a link module flanked with N-and C- extensions. These extensions are essential for folding and functional activity. CSPGs are characterized by an N-terminal globular domain (G1 domain) containing two contiguous link modules (modules 1 and 2). Both link modules of the G1 domain of the CSPG aggrecan are involved in interaction with HA. Aggrecan in addition contains a second globular domain (G2) which contains link modules 3 and 4 which lack HA-binding activity. HAPLNs contain two contiguous link modules.

54-165 1.76e-22

Immunoglobulin (Ig)-like domain of chondroitin sulfate proteoglycans (CSPGs), human cartilage link protein (LP), and similar domains; The members here are composed of the immunoglobulin (Ig)-like domain similar to that found in chondroitin sulfate proteoglycans (CSPGs) and human cartilage link protein (LP). Included in this group are the CSPGs aggrecan, versican, and neurocan. In CSPGs, this Ig-like domain is followed by hyaluronan (HA)-binding tandem repeats, and a C-terminal region with epidermal growth factor-like, lectin-like, and complement regulatory protein-like domains. Separating these N- and C-terminal regions is a nonhomologous glycosaminoglycan attachment region. In cartilage, aggrecan forms cartilage link protein stabilized aggregates with hyaluronan (HA). These aggregates contribute to the tissue's load bearing properties. Aggrecan and versican have a wide distribution in connective tissue and extracellular matrices. Neurocan is localized almost exclusively in nervous tissue. Aggregates having other CSPGs substituting for aggrecan may contribute to the structural integrity of many different tissues. There is considerable evidence that HA-binding CSPGs are involved in developmental processes in the central nervous system. Members of the vertebrate HPLN (hyaluronan/HA and proteoglycan binding link) protein family are physically linked adjacent to CSPG genes.

164-267 5.67e-18

This is the extracellular link domain of the type found in human TSG-6. The link domain is a hyaluronan (HA)-binding domain. TSG-6 is the protein product of tumor necrosis factor-stimulated gene-6. TSG-6 is up-regulated in inflammatory lesions and in the ovary during ovulation. It has a strong anti-inflammatory and chondroprotective effect in models of acute inflammation and autoimmune arthritis and plays an essential role in female fertility. Also included in this group are the stabilins: stabilin-1 (FEEL-1, CLEVER-1) and stabilin-2 (FEEL-2). Stabilin-2 functions as the major liver and lymph node-scavenging receptor for HA and related glycosaminoglycans. Stabilin-2 is a scavenger receptor with a broad range of ligands including advanced glycation end (AGE) products, acetylated low density lipoprotein and procollagen peptides. In contrast, stabilin-1 does not bind HA, but binds acetylated low density lipoprotein and AGEs with lower affinity. As AGEs accumulate in vascular tissues during aging and diabetes, these receptors may be implicated in the pathologies of these states. Both stabilins are present in the early endocytic pathway in hepatic sinusoidal epithelium associating with clathrin/AP-2. Stabilin-1 is expressed in macrophages. Stabilin-2 is absent from the latter. In macrophages: stabilin-1 is involved in trafficking between early/sorting endosomes and the trans-Golgi network. Stabilin-1 has also been implicated in angiogenesis and possibly leucocyte trafficking. Both stabilins bind gram-positive and gram-negative bacteria. TSG-6 and stabilins contain a single link module which supports high affinity binding to HA.

Immunoglobulin variable (IgV)-like domain in complement receptor of the immunoglobulin superfamily (CRIg); The members here are composed of the immunoglobulin variable (IgV) region of the complement receptor of the immunoglobulin superfamily (CRIg). The N-terminal domain of CRIg (also known as Z39Ig and V-set and Ig domain-containing 4 (VSIG4) belongs to the IgV family of immunoglobulin-like domains while the C-terminal domain of CRIg belongs to the IgC family of immunoglobulin-like domains. Like all members of this family, the CRIg domain contains two beta-sheets: one composed of strands A', G, F, C, C' and C", and the other of strands B, E and D. The complement system is an important part of the innate immune system and is required for removal of pathogens from the bloodstream. After exposure to pathogens, the third component of the complement system, C3, is cleaved to C3b which, after recruitment of factor B, initiates formation of the alternative pathway convertases. CRIg, a complement receptor expressed on macrophages, binds to C3b and iC3b mediating phagocytosis of the particles. It is also a potent inhibitor of the alternative pathway convertases and a negative regulator of T cell activation. The Ig superfamily is a heterogenous group of proteins, built on a common fold comprised of a sandwich of two beta sheets. Members of this group are components of immunoglobulin, neuroglia, cell surface glycoproteins, such as, T-cell receptors, CD2, CD4, CD8, and membrane glycoproteins, such as, butyrophilin and chondroitin sulfate proteoglycan core protein. A predominant feature of most Ig domains is a disulfide bridge connecting the two beta-sheets with a tryptophan residue packed against the disulfide bond.

53-165 4.21e-10

Immunoglobulin (Ig)-like domain of the aggrecan-like chondroitin sulfate proteoglycan core protein (CSPG); The members here are composed of the immunoglobulin (Ig)-like domain of the aggrecan-like chondroitin sulfate proteoglycan core proteins (CSPGs). Included in this group are the Ig domains of other CSPGs: versican, and neurocan. In CSPGs, this Ig-like domain is followed by hyaluronan (HA)-binding tandem repeats, and a C-terminal region with epidermal growth factor-like, lectin-like, and complement regulatory protein-like domains. Separating these N- and C-terminal regions is a nonhomologous glycosaminoglycan attachment region. In cartilage, aggrecan forms cartilage link protein stabilized aggregates with hyaluronan (HA). These aggregates contribute to the tissue's load bearing properties. Aggrecan and versican have a wide distribution in connective tissue and extracellular matrices. Neurocan is localized almost exclusively in nervous tissue. Aggregates having other CSPGs substituting for aggrecan may contribute to the structural integrity of many different tissues. Members of the vertebrate HPLN (hyaluronan/HA and proteoglycan binding link) protein family are physically linked adjacent to CSPG genes.

48-167 1.15e-07

Immunoglobulin Variable region-containing chitin-binding proteins; an immunoglobulin V-set domain; The members here are composed of the immunoglobulin variable (IgV) region-containing chitin-binding proteins (VCBPs). VCBPs are secreted, immune-type molecules that have been identified in both amphioxus and sea squirt (Ciona intestinalis). VCBPs, which consist of a leader peptide, two tandem N-terminal immunoglobulin V-type domains and a single C-terminal chitin-binding domain, belong to a multigene family encoding secreted proteins. The VCBPs were identified first in the cephalochordate Branchiostoma floridae and show structural similarities with V-type domains of immunoglobulins and T cell receptors, suggesting that VCBPs represent a unique gut-associated form of innate immune proteins. The Ig superfamily is a heterogenous group of proteins, built on a common fold comprised of a sandwich of two beta sheets. Members of this group are components of immunoglobulin, neuroglia, cell surface glycoproteins, such as, T-cell receptors, CD2, CD4, CD8, and membrane glycoproteins, such as, butyrophilin and chondroitin sulfate proteoglycan core protein. A predominant feature of most Ig domains is a disulfide bridge connecting the two beta-sheets with a tryptophan residue packed against the disulfide bond. IgSF domains can be divided into 4 main classes based on their structures and sequences: the Variable (V), Constant 1 (C1), Constant 2 (C2), and Intermediate (I) sets. This group belongs to the V-set of IgSF domains, having A, B, E and D strands in one beta-sheet and A', G, F, C, C' and C" in the other.

305-364 1.94e-07

This is the extracellular link domain of the type found in human TSG-6. The link domain is a hyaluronan (HA)-binding domain. TSG-6 is the protein product of tumor necrosis factor-stimulated gene-6. TSG-6 is up-regulated in inflammatory lesions and in the ovary during ovulation. It has a strong anti-inflammatory and chondroprotective effect in models of acute inflammation and autoimmune arthritis and plays an essential role in female fertility. Also included in this group are the stabilins: stabilin-1 (FEEL-1, CLEVER-1) and stabilin-2 (FEEL-2). Stabilin-2 functions as the major liver and lymph node-scavenging receptor for HA and related glycosaminoglycans. Stabilin-2 is a scavenger receptor with a broad range of ligands including advanced glycation end (AGE) products, acetylated low density lipoprotein and procollagen peptides. In contrast, stabilin-1 does not bind HA, but binds acetylated low density lipoprotein and AGEs with lower affinity. As AGEs accumulate in vascular tissues during aging and diabetes, these receptors may be implicated in the pathologies of these states. Both stabilins are present in the early endocytic pathway in hepatic sinusoidal epithelium associating with clathrin/AP-2. Stabilin-1 is expressed in macrophages. Stabilin-2 is absent from the latter. In macrophages: stabilin-1 is involved in trafficking between early/sorting endosomes and the trans-Golgi network. Stabilin-1 has also been implicated in angiogenesis and possibly leucocyte trafficking. Both stabilins bind gram-positive and gram-negative bacteria. TSG-6 and stabilins contain a single link module which supports high affinity binding to HA.

Immunoglobulin Variable (IgV) domain in HERV-H LTR-associating 2 (HHLA2); The members here are composed of the immunoglobulin variable (IgV) region in HERV-H LTR-associating 2 (HHLA2; also known as B7-H7/B7 homolog 7). HHLA2 is a member of the B7 family of immune regulatory proteins. Mature human HHLA2 consists of an extracellular domain (ECD) with three immunoglobulin-like domains, a transmembrane segment, and a cytoplasmic domain. HHLA2 is widely expressed in human cancers including non-small cell lung carcinoma (NSCLS), triple negative breast cancer (TNBC), and melanoma, but has limited expression on normal tissues. Interestingly, unlike other members of B7 family, HHLA2 is not expressed in mice or rats. HHLA2 functions as a T cell coinhibitory molecules as it inhibits the proliferation of activated CD4(+) and CD8(+) T cells and their cytokine production. Furthermore, HHLA2 is constitutively expressed on the surface of human monocytes and is induced on B cells after stimulation, however it is not inducible on T cells.

170-269 1.80e-05

This domain is a hyaluronan (HA)-binding domain. It is found in CD44 receptor and mediates adhesive interactions during inflammatory leukocyte homing and tumor metastasis. It also plays an important role in arteriogenesis. The functional HA-binding domain of CD44 is an extended domain comprised of a single link module flanked with N-and C- extensions. These extensions are essential for folding and for functional activity. This group also contains the cell surface retention sequence (CRS) binding protein-1 (CRSBP-1) and lymph vessel endothelial receptor-1 (LYVE-1). CRSBP-1 is a cell surface binding protein for the CRS motif of PDGF-BB (platelet-derived growth factor-BB) and is responsible for the cell surface retention of PDGF-BB in SSV-transformed cells. CRSBP-1 may play a role in autocrine regulation of cell growth mediated by CRS containing growth regulators. LYVE-1 is preferentially expressed on the lymphatic endothelium and is used as a molecular marker for the detection and characterization of lymphatic vessels in tumors.

Immunoglobulin domain; The members here are composed of the immunoglobulin (Ig) domain found in the Ig superfamily. The Ig superfamily is a heterogenous group of proteins, built on a common fold comprised of a sandwich of two beta sheets. Members of this group are components of immunoglobulin, neuroglia, cell surface glycoproteins, including T-cell receptors, CD2, CD4, CD8, and membrane glycoproteins, including butyrophilin and chondroitin sulfate proteoglycan core protein. A predominant feature of most Ig domains is a disulfide bridge connecting the two beta-sheets with a tryptophan residue packed against the disulfide bond. Ig superfamily (IgSF) domains can be divided into 4 main classes based on their structures and sequences: the Variable (V), Constant 1 (C1), Constant 2 (C2), and Intermediate (I) sets. Typically, the V-set domains have A, B, E, and D strands in one sheet and A', G, F, C, C' and C" in the other. The structures in C1-set are smaller than those in the V-set; they have one beta sheet that is formed by strands A, B, E, and D and the other by strands G, F, C, and C'. Moreover, a C1-set Ig domain contains a short C' strand (three residues) and lacks A' and C" strand. Unlike other Ig domain sets, C2-set structures do not have a D strand. Like the V-set Ig domains, members of the I-set have a discontinuous A strand, but lack a C" strand.

83-165 8.14e-05

Immunoglobulin (Ig)-like domain of the chondroitin sulfate proteoglycan core protein (CSPG), aggrecan; The members here are composed of the immunoglobulin (Ig)-like domain of the chondroitin sulfate proteoglycan core protein (CSPG), aggrecan. In CSPGs, the Ig-like domain is followed by hyaluronan (HA)-binding tandem repeats, and a C-terminal region with epidermal growth factor-like, lectin-like, and complement regulatory protein-like domains. Separating these N- and C-terminal regions is a nonhomologous glycosaminoglycan attachment region. In cartilage, aggrecan forms cartilage link protein stabilized aggregates with HA. These aggregates contribute to the tissue's load bearing properties. Aggrecan has a wide distribution in connective tissue and extracellular matrices. Members of the vertebrate HPLN (hyaluronan/HA and proteoglycan binding link) protein family are physically linked adjacent to CSPG genes.

First immunoglobulin (Ig) domain of nectin-4, and similar domains; The members here are composed of the first immunoglobulin (Ig) domain of nectin-4 (also known as poliovirus receptor related protein 4 or LNIR receptor). Nectin-4 belongs to the nectin family, which is comprised of four transmembrane glycoproteins (nectins-1 through -4). Nectins are synaptic cell adhesion molecules (CAMs) which participate in adhesion and signaling at various intracellular junctions. Nectins form homophilic cis-dimers, followed by homophilic and heterophilic trans-dimers involved in cell-cell adhesion. For example nectin-4 trans-interacts with nectin-1. Nectin-4 has also been shown to interact with the actin filament-binding protein, afadin. Unlike the other nectins, which are widely expressed in adult tissues, nectin-4 is mainly expressed during embryogenesis, and is not detected in normal adult tissue or in serum. Nectin-4 is re-expressed in breast carcinoma, and patients having metastatic breast cancer have a circulating form of nectin-4 formed from the ectodomain

Immunoglobulin (Ig)-like I-set domain of Neural Cell Adhesion Molecule 2 (NCAM-2); The members here are composed of the fourth Ig domain of Neural Cell Adhesion Molecule NCAM-2 (also known as OCAM/mamFas II and RNCAM). NCAM-2 is organized similarly to NCAM, including five N-terminal Ig-like domains and two fibronectin type III domains. NCAM-2 is differentially expressed in the developing and mature olfactory epithelium (OE), and may function like NCAM, as an adhesion molecule. One of the unique features of I-set domains is the lack of a C" strand. The structures of this group show that the Ig domain lacks this strand and thus is a member of the I-set of Ig domains.

47-144 6.03e-04

First immunoglobulin variable (IgV) domain of nectin-2, nectin-like protein 5, and similar domains; The members here are composed of the second immunoglobulin (Ig) domain of nectin-2 (also known as poliovirus receptor related protein 2 or Cluster of Differentiation 112 (CD112)), nectin-like protein 5 (CD155), and similar proteins. Nectins and Nectin-like molecules are a family of Ca(2+)-independent immunoglobulin-like transmembrane glycoproteins belonging to the class of adhesion receptors, consisting of nine members (nectins 1 through 4 and nectin-like proteins 1 through 5). Nectins are synaptic cell adhesion molecules (CAMs) which facilitate adhesion and signaling at various intracellular junctions. Nectins form homophilic cis-dimers, followed by homophilic and heterophilic trans-dimers involved in cell-cell adhesion. Nectin-2 and nectin-3 localize at Sertoli-spermatid junctions where they form heterophilic trans-interactions between the cells that are essential for the formation and maintenance of the junctions and for spermatid development. CD155 is the fifth member in the nectin-like molecule family, and functions as the receptor of poliovirus; therefore, CD155 is also referred to as Necl-5, or PVR. In contrast to all other family members, CD155 lacks self-adhesion capacity, yet it shares with nectins the feature to interact with other nectins. For instance, CD155 heterophilically trans-interacts with nectin-3, thereby contributing significantly to the establishment of adherens junctions between epithelial cells. This group belongs to the Constant 1 (C1)-set of IgSF domains, which has one beta-sheet that is formed by strands A-B-E-D and the other strands by G-F-C-C'.

Immunoglobulin (Ig)-like domain of carcinoembryonic antigen (CEA) related cell adhesion molecule (CEACAM) and similar proteins; The members here are composed of the immunoglobulin (Ig)-like domain in carcinoembryonic antigen (CEA) related cell adhesion molecule (CEACAM) and related domains. The CEA family is a group of anchored or secreted glycoproteins, expressed by epithelial cells, leukocytes, endothelial cells and placenta. The CEA family is divided into the CEACAM and pregnancy-specific glycoprotein (PSG) subfamilies. This group represents the CEACAM subfamily. CEACAM1 has many important cellular functions: it is a cell adhesion molecule and a signaling molecule that regulates the growth of tumor cells, an angiogenic factor, and a receptor for bacterial and viral pathogens, including mouse hepatitis virus (MHV). In mice, four isoforms of CEACAM1 generated by alternative splicing have either two (D1, D4) or four (D1-D4) Ig-like domains on the cell surface. This family corresponds to the D1 Ig-like domain. Also belonging to this group is the N-terminal immunoglobulin (Ig)-like domain of the signaling lymphocyte activation molecule (SLAM) family, CD84-like family. The SLAM family is a group of immune-cell specific receptors that can regulate both adaptive and innate immune responses. SLAM family proteins are organized as an extracellular domain with having two or four Ig-like domains, a single transmembrane segment, and a cytoplasmic region having Tyr-based motifs. The extracellular domain is organized as a membrane-distal Ig variable (IgV) domain that is responsible for ligand recognition and a membrane-proximal truncated Ig constant-2 (IgC2) domain.

Immunoglobulin Variable (IgV) domain of B7-H4; The members here are composed of the immunoglobulin variable (IgV) domain of B7-H4 (also known as B7-S1, B7x, or Vtcn1). B7-H4 is one of the B7 family of immune-regulatory ligands that act as negative regulators of T cell function; it contains one IgV domain and one IgC domain. The B7-family consists of structurally related cell-surface protein ligands, which bind to receptors on lymphocytes that regulate immune responses. The binding of B7-H4 to unidentified receptors results in the inhibition of TCR-mediated T cell proliferation, cell-cycle progression and IL-2 production. As a co-inhibitory molecule, B7-H4 is widely expressed in tumor tissues and its expression is significantly associated with poor prognosis in human cancers such as glioma, pancreatic cancer, oral squamous cell carcinoma, renal cell carcinoma, and lung cancer.

Immunoglobulin Variable (IgV) domain of Programmed death ligand 1 (PD-L1); The members here are composed of the immunoglobulin variable (IgV) domain of Programmed death ligand 1 (PD-L1; also known as Cluster of Differentiation 274 (CD274)). PD-L1 is a cell-surface ligand that competes with PD-L2 for binding to the immunosuppressive receptor programmed death-1 (PD-1). PD-1 is a member of the B7 family that plays an important role in negatively regulating immune responses upon interaction with its two ligands, PD-L1 or PD-L2. Like PD-L2, PD-L1 interacts with PD-1 and suppresses T cell proliferation and cytokine production. The PD-1 receptor is expressed on the surface of activated T cells, while PD-L1 is expressed on cancer cells. When PD-1 and PD-L1 bind together, they form a molecular shield protecting tumor cells from being destroyed by the immune system. Thus, inhibiting the binding of PD-L1 to PD-1 with an antibody leads to killing of tumor cells by T cells. PD-1 inhibitors (such as Pembrolizumab, Nivolumab, and Cemiplimab) and PD-L1 inhibitors (such as Atezolizumab, Avelumab, and Durvalumab ) are an emerging class of immunotherapy that stimulate lymphocytes against tumor cells.
