COMP cartilage oligomeric matrix protein

Gene ID: 1311, updated on 16-Apr-2024
Gene type: protein coding
Also known as: MED; CTS2; EDM1; EPD1; TSP5; PSACH; THBS5; TSP-5


The protein encoded by this gene is a noncollagenous extracellular matrix (ECM) protein. It consists of five identical glycoprotein subunits, each with EGF-like and calcium-binding (thrombospondin-like) domains. Oligomerization results from formation of a five-stranded coiled coil and disulfides. Binding to other ECM proteins such as collagen appears to depend on divalent cations. Contraction or expansion of a 5 aa aspartate repeat and other mutations can cause pseudochondroplasia (PSACH) and multiple epiphyseal dysplasia (MED). [provided by RefSeq, Jul 2016]
