Description: The HY101 monoclonal antibody reacts with the glycoprotein VI (GPVI), a 62-kDa type-I transmembrane glycoprotein that is expressed on mature megakaryotes and platelets. GPVI associates with the Fc receptor (FcR) gamma-chain to form a high affinity receptor for collagen. GPVI has also been reported to bind convulxin (Cvx). Phosphorylation of the ITAMs present on the FcR gamma-chain leads to recruitment of Src family kinases and activation of downstream signal transduction. GPVI has been reported to play a critical role in platelet activation and aggregation.
