COL2A1 [ENSP00000369889]
 
collagen, type II, alpha 1; Type II collagen is specific for cartilaginous tissues. It is essential for the normal embryonic development of the skeleton, for linear growth and for the ability of cartilage to resist compressive forces
COL11A1 [ENSP00000351163]
 
collagen, type XI, alpha 1; May play an important role in fibrillogenesis by controlling lateral growth of collagen II fibrils
