Predicted to be an extracellular matrix structural constituent. Involved in aging and response to activity. Predicted to be located in basement membrane. Predicted to be part of collagen type IV trimer. Predicted to be active in extracellular matrix and extracellular space. Human ortholog(s) of this gene implicated in atherosclerosis; brain small vessel disease 2; and porencephaly. Orthologous to human COL4A2 (collagen type IV alpha 2 chain).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
