最新研究進(jìn)展:COMP(Cartilage oligomeric matrix protein),又稱為Thrombospondin-5 (TSP5),是一種含有多個(gè)結(jié)構(gòu)域的分子,屬于類膠原蛋白家族。它主要在軟骨、肌腱和韌帶中表達(dá),并在軟骨發(fā)育、修復(fù)和代謝過(guò)程中起著重要作用。最近的研究表明,血液中的COMP水平可作為炎癥和代謝性疾病的標(biāo)志物,如類風(fēng)濕關(guān)節(jié)炎、膝關(guān)節(jié)骨性關(guān)節(jié)炎和2型糖尿病等。

功能: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.
