About COL4A2

Cytogenetic location: 13q34 Genomic coordinates (GRCh38): 13:110,307,284-110,513,209 (from NCBI)

This gene has 18 transcripts (splice variants), 163 orthologues, 37 paralogues and is associated with 4 phenotypes. Biased expression in placenta (RPKM 373.6), fat (RPKM 158.9) and 13 other tissues.

Summary

This gene encodes one of the six subunits of type IV collagen, the major structural component of basement membranes. The C-terminal portion of the protein, known as canstatin, is an inhibitor of angiogenesis and tumor growth. Like the other members of the type IV collagen gene family, this gene is organized in a head-to-head conformation with another type IV collagen gene so that each gene pair shares a common promoter.
