Integrin α-IIb (synonym CD41 ) is a surface protein from the group of integrins .
properties
Integrin α-IIb is a cell adhesion molecule and, together with integrin β-3, forms a heterodimeric receptor for fibronectin , fibrinogen , plasminogen , prothrombin , thrombospondin and vitronectin . Integrin α-IIb binds to the amino acid sequence RGD in various proteins and to HHLGGGAKQAGDV in the γ chain of fibrinogen. It is formed by platelets , megakaryocytes, and HSC ( pre-HSC type II ). Integrin α-IIb is glycosylated and has a pyrrolidone carboxylic acid .
