COL5A1 [ENSP00000360882]
collagen, type V, alpha 1; Type V collagen is a member of group I collagen (fibrillar forming collagen). It is a minor connective tissue component of nearly ubiquitous distribution. Type V collagen binds to DNA, heparan sulfate, thrombospondin, heparin, and insulin
COL11A1 [ENSP00000351163]
collagen, type XI, alpha 1; May play an important role in fibrillogenesis by controlling lateral growth of collagen II fibrils
