calponin homology (CH) domain found in molecule interacting with CasL protein 3; MICAL-3 is a [F-actin]-monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin to form methionine-sulfoxide, resulting in actin filament disassembly and preventing repolymerization. In the absence of actin, it also functions as a NADPH oxidase producing H(2)O(2). MICAL-3 seems to act as a Rab effector protein and plays a role in vesicle trafficking. It is involved in exocytic vesicle tethering and fusion. MICAL3 contains a single copy of the CH domain. CH domains are actin filament (F-actin) binding motifs.

The LIM domain of Mical (molecule interacting with CasL); The LIM domain of Mical (molecule interacting with CasL): MICAL is a large, multidomain, cytosolic protein with a single LIM domain, a calponin homology (CH) domain and a flavoprotein monooxygenase domain. In Drosophila, MICAL is expressed in axons, interacts with the neuronal A (PlexA) receptor and is required for Semapho-rin 1a (Sema-1a)-PlexA-mediated repulsive axon guidance. The LIM domain and calporin homology domain are known for interactions with the cytoskeleton, cytoskeletal adaptor proteins, and other signaling proteins. The flavoprotein monooxygenase (MO) is required for semaphorin-plexin repulsive axon guidance during axonal pathfinding in the Drosophila neuromuscular system. In addition, MICAL was characterized to interact with Rab13 and Rab8 to coordinate the assembly of tight junctions and adherens junctions in epithelial cells. Thus, MICAL was also named junctional Rab13-binding protein (JRAB). As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

chromosome segregation protein SMC, common bacterial 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. This family represents the SMC protein of most bacteria. The smc gene is often associated with scpB (TIGR00281) and scpA genes, where scp stands for segregation and condensation protein. SMC was shown (in Caulobacter crescentus) to be induced early in S phase but present and bound to DNA throughout the cell cycle.

calponin homology (CH) domain found in molecule interacting with CasL protein 3; MICAL-3 is a [F-actin]-monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin to form methionine-sulfoxide, resulting in actin filament disassembly and preventing repolymerization. In the absence of actin, it also functions as a NADPH oxidase producing H(2)O(2). MICAL-3 seems to act as a Rab effector protein and plays a role in vesicle trafficking. It is involved in exocytic vesicle tethering and fusion. MICAL3 contains a single copy of the CH domain. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in the MICAL and EHBP families; This group is composed of the molecule interacting with CasL protein (MICAL) and EH domain-binding protein (EHBP) families. 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. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in molecule interacting with CasL protein 2; MICAL-2 is a nuclear [F-actin]-monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin to form methionine-sulfoxide, resulting in actin filament disassembly and preventing repolymerization. In the absence of actin, it also functions as a NADPH oxidase producing H(2)O(2). MICAL-2 acts as a key regulator of the serum response factor (SRF) signaling pathway elicited by nerve growth factor and serum. It mediates oxidation and subsequent depolymerization of nuclear actin, leading to the increased MKL1/MRTF-A presence in the nucleus, promoting SRF:MKL1/MRTF-A-dependent gene transcription. MICAL-2 contains a single copy of the CH domain. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in the MICAL-like protein family; The MICAL-L family includes MICAL-L1 and MICAL-L2. MICAL-L1, also called molecule interacting with Rab13 (MIRab13), is a probable lipid-binding protein with higher affinity for phosphatidic acid, a lipid enriched in recycling endosome membranes. It is a tubular endosomal membrane hub that connects Rab35 and Arf6 with Rab8a. It may be involved in a late step of receptor-mediated endocytosis regulating endocytosed-EGF receptor trafficking. Alternatively, it may regulate slow endocytic recycling of endocytosed proteins back to the plasma membrane. MICAL-L1 may indirectly play a role in neurite outgrowth. MICAL-L2, also called junctional Rab13-binding protein (JRAB), or molecule interacting with CasL-like 2, acts as an effector of small Rab GTPases which is involved in junctional complexes assembly through the regulation of cell adhesion molecule transport to the plasma membrane, and actin cytoskeleton reorganization. It regulates the endocytic recycling of occludins, claudins, and E-cadherin to the plasma membrane and may thereby regulate the establishment of tight junctions and adherens junctions. Members of this family contain a single copy of CH domain. CH domains are actin filament (F-actin) binding motifs.

The LIM domain of Mical (molecule interacting with CasL); The LIM domain of Mical (molecule interacting with CasL): MICAL is a large, multidomain, cytosolic protein with a single LIM domain, a calponin homology (CH) domain and a flavoprotein monooxygenase domain. In Drosophila, MICAL is expressed in axons, interacts with the neuronal A (PlexA) receptor and is required for Semapho-rin 1a (Sema-1a)-PlexA-mediated repulsive axon guidance. The LIM domain and calporin homology domain are known for interactions with the cytoskeleton, cytoskeletal adaptor proteins, and other signaling proteins. The flavoprotein monooxygenase (MO) is required for semaphorin-plexin repulsive axon guidance during axonal pathfinding in the Drosophila neuromuscular system. In addition, MICAL was characterized to interact with Rab13 and Rab8 to coordinate the assembly of tight junctions and adherens junctions in epithelial cells. Thus, MICAL was also named junctional Rab13-binding protein (JRAB). As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

second calponin homology (CH) domain found in the alpha-actinin family; The alpha-actinin (ACTN) family includes alpha-actinin-1, -2, -3, and -4. They are F-actin cross-linking proteins which are thought to anchor actin to a variety of intracellular structures. ACTN1 mutations cause congenital macrothrombocytopenia. ACTN2 mutations are associated with cardiomyopathies, as well as skeletal muscle disorder. ACTN3 is critical in anchoring the myofibrillar actin filaments and plays a key role in muscle contraction. ACTN4 is associated with cell motility and cancer invasion. It is probably involved in vesicular trafficking via its association with the CART complex, which is necessary for efficient transferrin receptor recycling but not for epidermal growth factor receptor (EGFR) degradation. 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 beta spectrin family; The beta spectrin family includes beta-I, -II, -III, -IV and -V spectrins. 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. Beta-I spectrin, also called spectrin beta chain, erythrocytic (SPTB), may be involved in anaemia pathogenesis. Beta-II spectrin, also called spectrin beta chain, non-erythrocytic 1 (SPTBN1), or fodrin beta chain, is a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. Beta-IV spectrin is also called spectrin, non-erythroid beta chain 3 (SPTBN3) or spectrin beta chain, non-erythrocytic 4 (SPTBN4). Its mutation associates with congenital myopathy, neuropathy, and central deafness. Beta-III spectrin is also called spectrin beta chain, non-erythrocytic 2 (SPTBN2), or spinocerebellar ataxia 5 protein (SCA5). Beta-V spectrin, also called spectrin beta chain, non-erythrocytic 5 (SPTBN5), is a mammalian ortholog of Drosophila beta H spectrin. Beta-III and Beta-V spectrins may play crucial roles as longer actin-membrane cross-linkers or fulfill the need for greater extensible flexibility than can be provided by the other smaller conventional spectrins. 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 spectrin beta chain, non-erythrocytic 4 (SPTBN4) 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. SPTBN4, also called beta-IV spectrin, or spectrin, non-erythroid beta chain 3 (SPTBN3), is a novel spectrin isolated as an interactor of the receptor tyrosine phosphatase-like protein ICA512. Its mutation associates with congenital myopathy, neuropathy, and central deafness. SPTBN4 contains 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.
