Regulation Of Actin Cytoskeleton Pathway (198874)
ncbi summary :
This gene encodes a member of a family of calcium-regulated actin-binding proteins. This protein represents a dominant part of the brush border cytoskeleton which functions in the capping, severing, and bundling of actin filaments. Two mRNAs of 2.7 kb and 3.5 kb have been observed; they result from utilization of alternate poly-adenylation signals present in the terminal exon. [provided by RefSeq, Jul 2008]
uniprot summary :
Villin: Epithelial cell-specific Ca(2+)-regulated actin- modifying protein that modulates the reorganization of microvillar actin filaments. Plays a role in the actin nucleation, actin filament bundle assembly, actin filament capping and severing. Binds phosphatidylinositol 4,5-bisphosphate (PIP2) and lysophosphatidic acid (LPA); binds LPA with higher affinity than PIP2. Binding to LPA increases its phosphorylation by SRC and inhibits all actin-modifying activities. Binding to PIP2 inhibits actin-capping and -severing activities but enhances actin-bundling activity. Regulates the intestinal epithelial cell morphology, cell invasion, cell migration and apoptosis. Protects against apoptosis induced by dextran sodium sulfate (DSS) in the gastrointestinal epithelium. Appears to regulate cell death by maintaining mitochondrial integrity. Enhances hepatocyte growth factor (HGF)-induced epithelial cell motility, chemotaxis and wound repair. Upon S.flexneri cell infection, its actin-severing activity enhances actin-based motility of the bacteria and plays a role during the dissemination. Monomer. Homodimer; homodimerization is necessary for actin-bundling. Associates with F-actin; phosphorylation at tyrosines residues decreases the association with F-actin. Interacts (phosphorylated at C-terminus tyrosine phosphorylation sites) with PLCG1 (via the SH2 domains). Interacts (phosphorylated form) with PLCG1; the interaction is enhanced by hepatocyte growth factor (HGF). Specifically expressed in epithelial cells. Major component of microvilli of intestinal epithelial cells and kidney proximal tubule cells. Expressed in canalicular microvilli of hepatocytes. Belongs to the villin/gelsolin family. Protein type: Actin-binding; Motility/polarity/chemotaxis. Chromosomal Location of Human Ortholog: 2q35. Cellular Component: ruffle; filopodium tip; microvillus; lamellipodium; cytoplasm; actin filament bundle; filopodium. Molecular Function: actin filament binding; identical protein binding; phosphatidylinositol-4,5-bisphosphate binding; protein binding; protein homodimerization activity; caspase inhibitor activity; calcium ion binding. Biological Process: epidermal growth factor receptor signaling pathway; actin filament depolymerization; actin filament severing; actin filament capping; negative regulation of caspase activity; actin nucleation; regulation of cell shape; response to bacterium; epithelial cell differentiation; actin filament polymerization; positive regulation of actin filament bundle formation; regulation of actin nucleation; protein complex assembly; positive regulation of cell migration
