MeSH definition : 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.;
