EF-hand-like motif found in dystrophin; Dystrophin is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscle. It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. It involves in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). The dystrophin subfamily has been characterized by a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, dystrophin contains two syntrophin binding sites (SBSs) and a long N-terminal extension that comprises two actin-binding calponin homology (CH) domains, approximately 24 spectrin repeats (SRs) and a WW domain. Mutations in dystrophin lead to Duchenne muscular dystrophy (DMD). Moreover, dystrophin deficiency is associated abnormal cerebral diffusion and perfusion, acute Trypanosoma cruzi infection.

However, since they do not contain the canonical pattern of calcium binding residues found in many EF hand domains, they do not bind calcium ions. The main function of this domain is the provision of specificity in beta-dystroglycan recognition, though in dystrophin it serves an additional role: stabilization of the WW domain (pfam00397), enhancing dystroglycan binding.

EF-hand-like motif found in dystrophin; Dystrophin is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscle. It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. It involves in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). The dystrophin subfamily has been characterized by a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, dystrophin contains two syntrophin binding sites (SBSs) and a long N-terminal extension that comprises two actin-binding calponin homology (CH) domains, approximately 24 spectrin repeats (SRs) and a WW domain. Mutations in dystrophin lead to Duchenne muscular dystrophy (DMD). Moreover, dystrophin deficiency is associated abnormal cerebral diffusion and perfusion, acute Trypanosoma cruzi infection.

EF-hand-like motif found in the dystrophins subfamily; This dystrophins subfamily includes dystrophin and its two paralogs, utrophin and DRP-2. Dystrophin is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscle. It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. Dystrophin also involves in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Utrophin, also termed dystrophin-related protein 1 (DRP-1), is an autosomal dystrophin homologue that increases dystrophic muscle function and reduces pathology. It is broadly expressed at both the mRNA and protein levels, and occurs in the cerebrovascular endothelium. Utrophin forms the utrophin-glycoprotein complex (UGC) by interacting with the dystroglycans (DGs) and the sarcoglycan-dystroglycans, sarcoglycans and sarcospan (SG-SSPN) subcomplex. It may act as a scaffolding protein that stabilizes lipid microdomains and clusters mechanosensitive channel subunits, and link the F-actin cytoskeleton to the cell membrane via the associated glycoprotein complex. DRP-2 is mainly expressed in the vertebrate central nervous system (CNS). It is associated with brain membrane fractions and highly enriched in the postsynaptic density. DRP-2 plays a role in the organization of central cholinergic synapses. It interacts with dystroglycan and L-Periaxin to form a transmembrane complex, which plays a role in Schwann cell-basal lamina interactions and in the regulation of the terminal stages of myelination. The dystrophins subfamily has been characterized by a compact cluster of domains comprising a WW domain, four EF-hand-like motifs and a ZZ-domain, followed by two syntrophin binding sites (SBSs) and a looser region with two coiled-coils.

EF-hand-like motif found in the dystrophin/dystrobrevin/dystrotelin family; The dystrophin/dystrobrevin/dystrotelin family has been characterized by a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. Dystrophin is the founder member of this family. It is a sub-membrane cytoskeletal protein associated with the inner surface membrane. Dystrophin and its close paralog utrophin have a large N-terminal extension of actin-binding CH domains, up to 24 spectrin repeats, and a WW domain. Its further paralog, dystrophin-related protein 2 (DRP-2), retains only two of the spectrin repeats. Dystrophin, utrophin or DRP2 can form the core of a membrane-bound complex consisting of dystroglycan, sarcoglycans and syntrophins, known as the dystrophin-glycoprotein complex (DGC) that plays an important role in brain development and disease, as well as in the prevention of muscle damage. Dystrobrevins, including alpha- and beta-dystrobrevin, lack the large N-terminal extension found in dystrophin, but alpha-dystrobrevin has a characteristic C-terminal extension. Dystrobrevins are part of the DGC. They physically associate with members of the dystrophin family and with the syntrophins through their homologous C-terminal coiled coil motifs. In contrast, dystrotelins lack both the large N-terminal extension found in dystrophin and the obvious syntrophin-binding sites (SBSs). Dystrotelins are not critical for mammalian development. They may be involved in other forms of cytokinesis. Moreover, dystrotelin is unable to heterodimerize with members of the dystrophin or dystrobrevin families, or to homodimerize.

second calponin homology (CH) domain found in utrophin and similar proteins; Utrophin, also called dystrophin-related protein 1 (DRP-1), is an autosomal dystrophin homolog that increases dystrophic muscle function and reduces pathology. It is broadly expressed in both the mRNA and protein levels, and occurs in the cerebrovascular endothelium. Utrophin forms the utrophin-glycoprotein complex (UGC) by interacting with dystroglycans (DGs) and sarcoglycan-dystroglycans, as well as sarcoglycan and sarcospan (SG-SSPN) subcomplexes. It may act as a scaffolding protein that stabilizes lipid microdomains and clusters mechanosensitive channel subunits, and link the F-actin cytoskeleton to the cell membrane via the associated glycoprotein complex. Like dystrophin, utrophin has a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, it contains two syntrophin binding sites (SBSs) and a long N-terminal extension that comprises two actin-binding calponin homology (CH) domains, up to 24 spectrin repeats (SRs), and a WW domain. However, utrophin lacks the intrinsic microtubule binding activity of dystrophin SRs. This model corresponds to the second CH domain.

EF-hand; Members of this family adopt a helix-loop-helix motif, as per other EF hand domains. However, since they do not contain the canonical pattern of calcium binding residues found in many EF hand domains, they do not bind calcium ions. The main function of this domain is the provision of specificity in beta-dystroglycan recognition, though in dystrophin it serves an additional role: stabilization of the WW domain (pfam00397), enhancing dystroglycan binding.

second calponin homology (CH) domain found in the plectin/dystonin/MACF1 family; This family includes plectin, dystonin and microtubule-actin cross-linking factor 1, isoforms 1/2/3/5 (MACF1). Plectin, also called PCN, PLTN, hemidesmosomal protein 1 (HD1), or plectin-1, is a structural component of muscle. It interlinks intermediate filaments with microtubules and microfilaments, and anchors intermediate filaments to desmosomes or hemidesmosomes. It could also bind muscle proteins such as actin to membrane complexes in muscle. Dystonin, also called 230 kDa bullous pemphigoid antigen, 230/240 kDa bullous pemphigoid antigen, bullous pemphigoid antigen 1 (BPA or BPAG1), dystonia musculorum protein, or hemidesmosomal plaque protein, is a cytoskeletal linker protein that acts as an integrator of intermediate filaments, actin, and microtubule cytoskeleton networks. It is required for anchoring either intermediate filaments to the actin cytoskeleton in neural and muscle cells, or keratin-containing intermediate filaments to hemidesmosomes in epithelial cells. MACF1, also called 620 kDa actin-binding protein (ABP620), actin cross-linking family protein 7 (ACF7), macrophin-1, or trabeculin-alpha, is a large protein containing numerous spectrin and leucine-rich repeat (LRR) domains. It facilitates actin-microtubule interactions at the cell periphery and couples the microtubule network to cellular junctions. Members of this family contain two copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

second calponin homology (CH) domain found in the filamin family; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. This family also includes Drosophila melanogaster protein jitterbug (Jbug), which is an actin-meshwork organizing protein containing three copies of the CH domain. Other members of this family contain two copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in molecule interacting with CasL protein 2 (MICAL-2), MICAL-3, and similar proteins; Molecule interacting with CasL protein (MICAL) is a large, multidomain, cytosolic protein with a single LIM domain, a calponin homology (CH) domain and a flavoprotein monooxygenase (MO) domain. In Drosophila, MICAL is expressed in axons, interacts with the neuronal A (PlexA) receptor and is required for Semaphorin 1a (Sema-1a)-PlexA-mediated repulsive axon guidance. The LIM and CH domains mediate interactions with the cytoskeleton, cytoskeletal adaptor proteins, and other signaling proteins. The flavoprotein MO is required for semaphorin-plexin repulsive axon guidance during axonal pathfinding in the Drosophila neuromuscular system. In addition, MICAL functions to interact with Rab13 and Rab8 to coordinate the assembly of tight junctions and adherens junctions in epithelial cells. Thus, MICAL is also called junctional Rab13-binding protein (JRAB). Members of this family, which includes MICAL-2, MICAL-3, and similar proteins, contain one CH domain. CH domains are actin filament (F-actin) binding motifs.

The family includes two paralogs dystrobrevins, alpha- and beta-dystrobrevin, both of which are cytoplasmic components of the dystrophin-associated protein complex that function as scaffold proteins in signal transduction and intracellular transport. Absence of alpha- and beta-dystrobrevin causes cerebellar synaptic defects and abnormal motor behavior. The dystrobrevins subfamily has been characterized by a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, dystrobrevins contain one or two syntrophin binding sites (SBSs).

Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, or LC64P, or lymphocyte cytosolic protein 1 (LCP-1), is an actin-binding protein that plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is an actin-bundling protein found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5, which cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the third CH domain. CH domains are actin filament (F-actin) binding motifs.

second calponin homology (CH) domain found in filamins; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. Members of this family contain two copies of the CH domain. The model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

EF-hand-like motif found in dystrotelin and similar proteins; Dystrotelin is the vertebrate orthologue of Drosophila DAH, which is involved in the synchronised cellularization of thousands of nuclei in the syncytial early fly embryo (a specialised form of cytokinesis). Dystrotelin is mainly expressed in the developing central nervous system (CNS) and adult nervous and muscular tissues. Heterologously expressed dystrotelin protein localizes spontaneously to the cytoplasmic membrane, and possibly to the endoplasmic reticulum (ER). Dystrotelin is not critical for mammalian development. It may be involved in other forms of cytokinesis. Its N-terminal region contains a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. The C-terminal region is extremely divergent. Unlike other superfamily members, dystrophin or dystrobrevin, the residues directly involved in beta-dystroglycan binding are not conserved in dystrotelin, which makes it unlikely that dystrotelin interacts with this ligand. Moreover, dystrotelin is unable to heterodimerize with members of the dystrophin or dystrobrevin families, or to homodimerize.

EF-hand-like motif found in alpha-dystrobrevin; Alpha-dystrobrevin, also termed dystrobrevin alpha (DTN-A), or dystrophin-related protein 3 (DRP-3), is the mammalian ortholog of the Torpedo 87 kDa postsynaptic protein that tightly associates with dystrophin. It is a cytoplasmic protein expressed predominantly in skeletal muscle, heart, lung, and brain. Alpha-dystrobrevin has been implicated in the regulation of acetylcholine receptor (AChR) aggregate density and patterning. It is also essential in the pathogenesis of dystrophin-dependent muscular dystrophies. It plays a critical role in the full functionality of dystrophin through increasing dystrophin's binding to the dystrophin-glycoprotein complex (DGC), and provides protection during cardiac stress. Alpha-dystrobrevin binds to the intermediate filament proteins syncoilin and beta-synemin, thereby linking the dystrophin-associated protein complex (DAPC) to the intermediate filament network. Moreover, alpha-dystrobrevin involves in cell signaling via interaction with other proteins such as syntrophin, a modular adaptor protein that coordinates the assembly of the signaling proteins nitric oxide synthase, stress-activated protein kinase-3, and Grb2 to the DAPC. Furthermore, alpha-dystrobrevin plays an important role in muscle function, as well as in nuclear morphology maintenance through specific interaction with the nuclear lamina component lamin B1. In addition, alpha-dystrobrevin is required in dystrophin-associated protein scaffolding in brain. Absence of glial alpha-dystrobrevin causes abnormalities of the blood-brain barrier and progressive brain edema. Alpha-dystrobrevin has a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, alpha-dystrobrevin contain two syntrophin binding sites (SBSs).

EF-hand-like motif found in beta-dystrobrevin; Beta-dystrobrevin, also termed dystrobrevin beta (DTN-B), is a dystrophin-related protein that is restricted to non-muscle tissues and is abundantly expressed in brain, lung, kidney, and liver. It may be involved in regulating chromatin dynamics, possibly playing a role in neuronal differentiation, through the interactions with the high mobility group HMG20 proteins iBRAF/HMG20a and BRAF35 /HMG20b. It also binds to and represses the promoter of synapsin I, a neuronal differentiation gene. Moreover, beta-dystrobrevin functions as a kinesin-binding receptor involved in brain development via the association with the extracellular matrix components pancortins. Furthermore, beta-dystrobrevin binds directly to dystrophin and is a cytoplasmic component of the dystrophin-associated glycoprotein complex, a multimeric protein complex that links the extracellular matrix to the cortical actin cytoskeleton and acts as a scaffold for signaling proteins such as protein kinase A. Absence of alpha- and beta-dystrobrevin causes cerebellar synaptic defects and abnormal motor behavior. Beta-dystrobrevin has a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, beta-dystrobrevin contain two syntrophin binding sites (SBSs).

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

second calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5; they cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.
