Gene: Col9a1 (collagen type IX alpha 1 chain) Rattus norvegicus
Symbol: Col9a1
Name: collagen type IX alpha 1 chain
CRRD ID: 1309425
Description: Predicted to have extracellular matrix structural constituent. Involved in chondrocyte differentiation. Predicted to localize to basement membrane; collagen type IX trimer; and extracellular space. Human ortholog(s) of this gene implicated in Stickler syndrome; multiple epiphyseal dysplasia 6; and osteochondrodysplasia. Orthologous to human COL9A1 (collagen type IX alpha 1 chain); PARTICIPATES IN syndecan signaling pathway; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 2,3,7,8-Tetrachlorodibenzofuran; bisphenol A.
Type: protein-coding
RefSeq Status: VALIDATED
