COMP - Cartilage oligomeric matrix protein - is a prominent multidomain glycoprotein of cartilage, accounting for up to 1% of the wet weight of articular tissues and having an approximate Mr of 97 kDa. COMP may also be found in tendon, bone (i.e. osteoblasts), ligament, certain smooth muscles and synovium. In the ECM COMP is present in a pentameric, disulfide-bonded complex of an Mr of about 550 kDa.
