Platelet Membrane Glycoprotein IIb is an integrin alpha subunit that heterodimerizes with Integrin beta3 to form Platelet Glycoprotein GPIIb-IIIa Complex. It is synthesized as a single polypeptide chain which is then postranslationally cleaved and processed into two disulfide-linked subunits of approximately 18 and 110 kDa in size.
