second calponin homology (CH) domain found in spectrin beta chain, non-erythrocytic 2 (SPTBN2) and similar proteins; Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. SPTBN2, also called beta-III spectrin, or spinocerebellar ataxia 5 protein (SCA5), probably plays an important role in the neuronal membrane skeleton. Mutations in SPTBN2 is associated with spinocerebellar ataxia type 5. SPTBN2 contains two copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs. : Pssm-ID: 409170 Cd Length: 119 Bit Score: 268.08 E-value: 1.84e-83

calponin homology (CH) domain superfamily; CH domains are actin filament (F-actin) binding motifs, which may be present as a single copy or in tandem repeats (which increase binding affinity). They either function as autonomous actin binding motifs or serve a regulatory function. CH domains are found in cytoskeletal and signal transduction proteins, including actin-binding proteins like spectrin, alpha-actinin, dystrophin, utrophin, and fimbrin, as well as proteins essential for regulation of cell shape (cortexillins), and signaling proteins (Vav).

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.

first calponin homology (CH) domain found in dystrophin and similar proteins; Dystrophin, encoded by the DMD gene, is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscles. 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 is involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Mutations in dystrophin lead to Duchenne muscular dystrophy (DMD). Moreover, dystrophin deficiency is associated with abnormal cerebral diffusion and perfusion, as well as in acute Trypanosoma cruzi infection. 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.

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. The EHBP family includes EHBP1 and EHBP1-like protein (EHBP1L1). EHBP1 is a regulator of endocytic recycling and may play a role in actin reorganization by linking clathrin-mediated endocytosis to the actin cytoskeleton. It may act as an effector of small GTPases, including RAB-10 (Rab10), and play a role in vesicle trafficking. EHBP proteins contain a single CH domain.

second calponin homology (CH) domain found in dystrophin and similar proteins; Dystrophin, encoded by the DMD gene, is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscles. 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 is involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Mutations in dystrophin lead to Duchenne muscular dystrophy (DMD). Moreover, dystrophin deficiency is associated with abnormal cerebral diffusion and perfusion, as well as in acute Trypanosoma cruzi infection. 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. The model corresponds to the second CH domain. Pssm-ID: 409082 Cd Length: 111 Bit Score: 120.42 E-value: 7.59e-32

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.

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.

67-153 | 1.18e-04 | ||||||||||||
first calponin homology (CH) domain found in the parvin family; The parvin family includes alpha-parvin, beta-parvin, and gamma-parvin. Alpha-parvin, also called actopaxin, calponin-like integrin-linked kinase-binding protein (CH-ILKBP), or matrix-remodeling-associated protein 2, plays a role in sarcomere organization and in smooth muscle cell contraction. It is required for normal development of the embryonic cardiovascular system, and for normal septation of the heart outflow tract. Beta-parvin, also called affixin, is an adapter protein that plays a role in integrin signaling via ILK and in activation of the GTPases Cdc42 and Rac1 by guanine exchange factors, such as ARHGEF6. Both alpha-parvin and beta-parvin are involved in the reorganization of the actin cytoskeleton and the formation of lamellipodia, and both play roles in cell adhesion, cell spreading, establishment or maintenance of cell polarity, and cell migration. Gamma-parvin probably plays a role in the regulation of cell adhesion and cytoskeleton organization. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs. Pssm-ID: 409070 Cd Length: 106 Bit Score: 42.65 E-value: 1.18e-04

Mitotic checkpoint protein; This family consists of several eukaryotic mitotic checkpoint (Mitotic arrest deficient or MAD) proteins. The mitotic spindle checkpoint monitors proper attachment of the bipolar spindle to the kinetochores of aligned sister chromatids and causes a cell cycle arrest in prometaphase when failures occur. Multiple components of the mitotic spindle checkpoint have been identified in yeast and higher eukaryotes. In S.cerevisiae, the existence of a Mad1-dependent complex containing Mad2, Mad3, Bub3 and Cdc20 has been demonstrated.

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.
