Background: 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 activated platelets. The CD61 antigen is also found on endothelial cells, megakaryocytes, on some myeloid, erythroid and T-lymphoid leukemic cell lines.
