Function

Plays 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 (PubMed:16051604, PubMed:16542502). Could play a role in the pathogenesis of osteoarthritis (PubMed:16542502). 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) (PubMed:17993464). 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).

Notes

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

- High batch-to-batch consistency and reproducibility
- Improved sensitivity and specificity
- Long-term security of supply
- Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar^® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar^® is a trademark of Fluidigm Canada Inc.

Activity summary

The Cartilage Oligomeric Matrix Protein (COMP) also known as oligomeric protein or COMP cartilage protein is a structural component found in the extracellular matrix of cartilage tissues. This matrix protein has a mass of approximately 524 kDa and is predominantly expressed in cartilage particularly hyaline cartilage. COMP forms pentameric structures which make it an important supporting element in the stability and resilience of cartilage. Researchers often use techniques like COMP ELISA to quantify its levels in biological samples.

Biological function summary

COMP interacts with other extracellular matrix components to enhance structural integrity and function of cartilage tissue. It performs significant roles in the organization and maintenance of the matrix tethering fibrillar proteins and supporting cellular interaction. COMP is not typically part of a large complex but works closely with collagens and other matrix proteins to form a robust and flexible extracellular environment.

Pathways

COMP participates in pathways associated with cartilage formation and turnover. It engages in chondrocyte-mediated processes that are vital for endochondral ossification and cartilage repair. Within these pathways it interacts with proteins such as collagen type II and decorin which facilitate the organization and mineralization of cartilage matrix. These interactions highlight the protein's importance in maintaining cartilage architecture and function.

Associated diseases and disorders

COMP plays a role in chondrodysplasias and osteoarthritis. Mutations in the COMP gene can lead to skeletal disorders like pseudoachondroplasia and multiple epiphyseal dysplasia causing growth and developmental anomalies. In osteoarthritis alterations in COMP levels may serve as an indicator of cartilage degradation. COMP's relationships with proteins like aggrecan and matrilin-3 in these contexts highlight its involvement in pathologies that affect cartilage structure and health.
