FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygous null mutants do not exhibit gross abnormalities or apparent defects of microvilli morphogenesis, however in one line, an increased sensitivity to colitis induced by dextran sulfate was observed. [provided by MGI curators]
