Cartilage oligomeric matrix protein (COMP) is a member of the thrombospondin family of extracellular matrix proteins.
The protein consists of five 87kD subunits held together by interchain disulfide bonds, forming a 435kD pentameric protein.
COMP is expressed in all types of cartilage, vitreous of the eye, tendon, and vascular smooth muscle cells
Immunohistological staining of articular cartilage has revealed a developmentally regulated localization of COMP to the chondrocyte territorial and interterritorial matrix.
COMP binds in a zinc-dependent manner to collagen type I and type II and also to collagen type IX.
The thrombospondin family currently includes five members: TSP-1, TSP-2, TSP-3, TSP-4, and COMP (also referred to as TSP-5).
