Summary: Enables fibronectin binding activity and vitamin D binding activity. An extracellular matrix structural constituent. Predicted to be involved in cartilage homeostasis; negative regulation of apoptotic process; and protein homooligomerization. Predicted to act upstream of or within several processes, including BMP signaling pathway; cartilage development; and vasculature development. Located in collagen-containing extracellular matrix. Human ortholog(s) of this gene implicated in carpal tunnel syndrome 2; multiple epiphyseal dysplasia 1; osteochondrodysplasia; and pseudoachondroplasia. Orthologous to human COMP (cartilage oligomeric matrix protein). [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.
