Gene: COL4A2 (collagen type IV alpha 2 chain) Homo sapiens
Symbol: COL4A2
Name: collagen type IV alpha 2 chain
Description: Exhibits extracellular matrix structural constituent conferring tensile strength. Involved in endodermal cell differentiation and negative regulation of angiogenesis. Localizes to the collagen-containing extracellular matrix and extracellular exosome. Implicated in atherosclerosis and porencephaly.
Type: protein-coding
RefSeq Status: REVIEWED
