Summary: Predicted to enable several functions, including MHC class II protein binding activity; platelet-derived growth factor binding activity; and protein homodimerization activity. Predicted to be an extracellular matrix structural constituent conferring tensile strength. Involved in several processes, including cartilage development; cellular response to insulin-like growth factor stimulus; and cellular response to mechanical stimulus. Located in collagen-containing extracellular matrix. Used to study degenerative disc disease; hypothyroidism; and osteoarthritis. Biomarker of degenerative disc disease and osteonecrosis. Human ortholog(s) of this gene implicated in Stickler syndrome (multiple); bone disease (multiple); cleft palate; eye disease (multiple); and multiple epiphyseal dysplasia with myopia and deafness. Orthologous to human COL2A1 (collagen type II alpha 1 chain). [provided by Alliance of Genome Resources, Dec 2024]

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.
