NCBI and Uniprot Product Information
NCBI Description
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, Jul 2008]
Uniprot Description
COMP: 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. Defects in COMP are the cause of multiple epiphyseal dysplasia type 1 (EDM1). 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). 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. Belongs to the thrombospondin family.

Product Notes
The COMP comp (Catalog #AAA224829) is an Antibody produced from Rat and is intended for research purposes only. The product is available for immediate purchase. The RAT ANTI HUMAN CARTILAGE OLIGOMERIC MATRIX PROTEIN reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's CARTILAGE OLIGOMERIC MATRIX PROTEIN can be used in a range of immunoassay formats including, but not limited to, Immunohistochemistry (IHC) Formalin/Paraffin, ELISA (EIA), Immunoprecipitation (IP), Western Blot (WB). Western Blot: 1/200; 1/2000. Researchers should empirically determine the suitability of the COMP comp for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CARTILAGE OLIGOMERIC MATRIX PROTEIN, Monoclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
