Wikidata
Platelet glycoprotein Ib alpha chain also known as glycoprotein Ib (platelet), alpha polypeptide or CD42b (C luster of D ifferentiation 42b ), is a
protein that in humans is encoded by the GP1BA
gene .
Function
Glycoprotein Ib (GP Ib) is a platelet surface membrane glycoprotein receptor composed of a heterodimer, an alpha chain and a beta chain, that are linked by disulfide bonds.
[5] The Gp Ib functions as a receptor for
von Willebrand factor (VWF). The complete receptor complex includes noncovalent association of the alpha and beta subunits with platelet glycoprotein IX and platelet glycoprotein V to form the
glycoprotein Ib-IX-V complex . Binding of the GP Ib-IX-V complex to VWF facilitates initial platelet adhesion to vascular subendothelium after vascular injury,
[6] and also initiates signaling events within the platelet that lead to enhanced platelet activation, thrombosis, and hemostasis.
[7] This gene encodes the alpha subunit. Several polymorphisms and mutations have been described in this gene, some of which are the cause of
Bernard–Soulier syndromes and platelet-type
von Willebrand disease .
