View All» Clone: 484D1 View All» Isotype: IgG1κ View All» Background Information: Cartilage oligomeric matrix protein (COMP, Thrombospondin-5, TSP5) is a member of the thrombospondin gene family. COMP is usually found in the extracellular matrix and is regularly linked to cartilage tissue. COMP seems to protect chondrocytes against cell death, whether tumor necrosis factor alpha is present or not. Defects in COMP are the cause of multiple epiphyseal dysplasia type 1 and pseudoachondroplasia.

      View All» Entrez Gene Summary: 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. Mutations can cause the osteochondrodysplasias pseudochondroplasia (PSACH) and multiple epiphyseal dysplasia (MED). [provided by RefSeq]. View All» UniProt Summary: FUNCTION: May play a role in the structural integrity of cartilage via its interaction with other extracellular matrix proteins such as the collagens and fibronectin. Can mediate the interaction of chondrocytes with the cartilage extracellular matrix through interaction with cell surface integrin receptors. Could play a role in the pathogenesis of osteoarthritis. Potent suppressor of apoptosis in both primary chondrocytes and transformed cells. Suppresses apoptosis by blocking the activation of caspase-3 and by inducing the IAP family of survival proteins (BIRC3, BIRC2, BIRC5 and XIAP). Essential for maintaining a vascular smooth muscle cells (VSMCs) contractile/differentiated phenotype under physiological and pathological stimuli. Maintains this phenotype of VSMCs by interacting with ITGA7 (By similarity). COFACTOR: Binds 11-14 calcium ions per subunit.SUBUNIT STRUCTURE: Pentamer; disulfide-linked. Exists in a more compact conformation in the presence of calcium and shows a more extended conformation in the absence of calcium. Interacts with ITGB3, ITGA5 and FN1. Binding to FN1 requires the presence of divalent cations (Ca2+, Mg2+ or Mn2+). The greatest amount of binding is seen in the presence of Mn2+. Interacts with MATN1, MATN3, MATN4 and ACAN. Binds heparin, heparan sulfate and chondroitin sulfate. EDTA dimishes significantly its binding to ACAN and abolishes its binding to MATN3, MATN4 and chondroitin sulfate. Interacts with collagen I, II and IX, and interaction with these collagens is dependent on the presence of zinc ions. Interacts with ADAMTS12. Interacts with ITGA7 (By similarity). SUBCELLULAR LOCATION: Secreted › extracellular space › extracellular matrix. TISSUE SPECIFICTY: Abundantly expressed in the chondrocyte extracellular matrix, and is also found in bone, tendon, ligament and synovium and blood vessels. Increased amounts are produced during late stages of osteoarthritis in the area adjacent to the main defect. DEVELOPMENTAL STAGE: Present during the earliest stages of limb maturation and is later found in regions where the joints develop. DOMAIN: The cell attachment motif mediates the attachment to chondrocytes. It mediates the induction of both the IAP family of survival proteins and the antiapoptotic response. The TSP C-terminal domain mediates interaction with FN1 and ACAN. INVOLVEMENT IN DISEASE: Defects in COMP are the cause of multiple epiphyseal dysplasia type 1 (EDM1) [MIM:132400]. EDM is a generalized skeletal dysplasia associated with significant morbidity. Joint pain, joint deformity, waddling gait, and short stature are the main clinical signs and symptoms. EDM is broadly categorized into the more severe Fairbank and the milder Ribbing types. Defects in COMP are the cause of pseudoachondroplasia (PSACH) [MIM:177170]. PSAC is a dominantly inherited chondrodysplasia characterized by short stature and early-onset osteoarthrosis. PSACH is more severe than EDM1 and is recognized in early childhood. SEQUENCE SIMILARITIES: Belongs to the thrombospondin family.Contains 4 EGF-like domains.Contains 1 TSP C-terminal (TSPC) domain.Contains 8 TSP type-3 repeats.SEQUENCE CAUTION: The sequence AAB86501.1 differs from that shown. Reason: Erroneous gene model prediction.
