MGI Phenotype FUNCTION: This gene encodes the alpha-2 subunit of the type IV collagens, an essential component of basement membranes. The encoded protein forms a triple helical heterotrimer comprised of alpha-1 and alpha-2 subunits that assembles into a type IV collagen network. Canstatin, a peptide derived fom the C-terminus of the collagen chain, is a matrikine that has been shown to inhibit angiogenesis. Homozygous knockout mice for this gene exhibit impaired basement membrane integrity and embryonic lethality. This gene shares a bi-directional promoter with a related gene on chromosome 8.

PHENOTYPE: ENU-induced missense mutations of this gene result in a variable phenotype affecting the eye, brain and vascular stability in heterozygotes, and fetal or postnatal survival in homozygotes. [provided by MGI curators]
