MGI Phenotype Strain: 3526405
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The product of this gene belongs to the syntaxin/epimorphin family of proteins. The syntaxins are a large protein family implicated in the targeting and fusion of intracellular transport vesicles. The product of this gene regulates epithelial-mesenchymal interactions and epithelial cell morphogenesis and activation. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a null allele display male infertility associated with abnormal testicular development and impaired spermatogenesis, increased intestinal growth due to enhanced crypt cell proliferation and crypt fission, and decreased susceptibility to induced colitis.
