Description | CD61 recognizes an Mr 110-kdalton (kDa) protein, also known as gpIIIa, the common subunit (integrin 3-chain) of the gpIIb/IIIa complex and the vitronectin receptor (VNR). The gpIIb/IIIa complex and the VNR are integrins, ie, a/b-heterodimeric glycoprotein complexes that are involved in cell adhesion. With the CD41 antigen (gpIIb or aIIb), the CD61 antigen forms the gpIIb/IIIa complex, which acts as a receptor for fibrinogen, von Willebrand factor (vWf), fibronectin and vitronectin on activated platelets. With the CD51 antigen (VNR a-chain or av), the CD61 antigen forms the VNR, which mediates activation-independent cell adhesion to vitronectin, vWf, fibrinogen, and thrombospondin. The CD61 antigen is found on all normal resting and activa |
