Cartilage oligomeric matrix protein (COMP), also known as thrombospondin-5, is an extracellular matrix (ECM) protein primarily present in cartilage. In humans it is encoded by the COMPgene.[1][2][3]
COMP is a marker of cartilage turnover.[5] It is present in high quantities in fibrotic scars and systemic sclerosis, and it appears to have a role in vascular wall remodeling.[6]
