Also known as: Col8a-1
Summary: Predicted to be an extracellular matrix structural constituent conferring tensile strength. Acts upstream of or within camera-type eye morphogenesis; endothelial cell proliferation; and positive regulation of cell-substrate adhesion. Located in collagen-containing extracellular matrix and extracellular space. Is expressed in several structures, including brain; craniocervical region bone; gut; heart; and limb mesenchyme. Orthologous to human COL8A1 (collagen type VIII alpha 1 chain). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in bladder adult (RPKM 10.3), limb E14.5 (RPKM 3.6) and 13 other tissues See more

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.
