======= COL9A3 ======= == Gene Information == * **Official Symbol**: COL9A3 * **Official Name**: collagen type IX alpha 3 chain * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=1299|1299]] * **UniProt**: [[https://www.uniprot.org/uniprot/Q14050|Q14050]] * **Interactions**: [[https://thebiogrid.org/search.php?search=COL9A3&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20COL9A3|Open PubMed]] * **OMIM**: [[https://omim.org/entry/120270|Open OMIM]] == Function Summary == * **Entrez Summary**: This gene encodes one of the three alpha chains of type IX collagen, the major collagen component of hyaline cartilage. Type IX collagen, a heterotrimeric molecule, is usually found in tissues containing type II collagen, a fibrillar collagen. Mutations in this gene are associated with multiple epiphyseal dysplasia type 3. [provided by RefSeq, Jan 2010]. * **UniProt Summary**: Structural component of hyaline cartilage and vitreous of the eye. |Collagen| |collagen type IX trimer| |extracellular matrix structural constituent conferring tensile strength| |female gonad development| |development of primary female sexual characteristics| |female sex differentiation| |extracellular matrix structural constituent| |male gonad development| |development of primary male sexual characteristics| |male sex differentiation| |gonad development| |development of primary sexual characteristics| |extracellular matrix| |sex differentiation| |endoplasmic reticulum lumen| |extracellular matrix organization| |collagen-containing extracellular matrix| |extracellular structure organization| |reproductive structure development| |reproductive system development| |developmental process involved in reproduction| |reproductive process| |reproduction| |extracellular space| |extracellular region| \\ === CRISPR Data === No hits were found.
