Villin Rabbit Polyclonal Antibody

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], domain:Consists of a large core fragment, the N-terminal portion, and a small headpiece, the C-terminal portion. The headpiece binds F-actin strongly in both the presence and absence of calcium., function:Ca (2+) -regulated actin-binding protein., similarity:Belongs to the villin/gelsolin family., similarity:Contains 1 HP (headpiece) domain., similarity:Contains 6 gelsolin-like repeats., subunit:Monomer., tissue specificity:Major component of microvilli of intestinal epithelial cells and kidney proximal tubule cells.
