MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a structural protein that is found exclusively in contractile smooth muscle cells. It associates with stress fibers and constitutes part of the cytoskeleton. This gene is localized to chromosome 22q12.3, distal to the TUPLE1 locus and outside the DiGeorge syndrome deletion. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, May 2011]
PHENOTYPE: Mice homozygous for disruptions of both the A and B isoforms of this gene display partial postnatal lethality, impaired intestinal smooth muscle contractility and thus hampered intestinal transit and diverticulosis. Mice lacking only the B isoform appearnormal. [provided by MGI curators]
