Gene: Col9a3 (collagen type IX alpha 3 chain) Rattus norvegicus
Symbol: Col9a3
Name: collagen type IX alpha 3 chain
Description: Predicted to have extracellular matrix structural constituent. Predicted to be involved in extracellular matrix organization; female gonad development; and male gonad development. Predicted to localize to the collagen type IX trimer; extracellular matrix; and extracellular space. Human ortholog(s) of this gene implicated in multiple epiphyseal dysplasia 3 and osteochondrodysplasia. Orthologous to human COL9A3 (collagen type IX alpha 3 chain); INTERACTS WITH 17alpha-ethynylestradiol; bisphenol A; lead diacetate.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: collagen alpha-3(IX) chain; collagen, type IX, alpha 3; LOC362285; procollagen, type IX, alpha 3
