Glycoprotein Ib (GPIb), also known as CD42,[1]
is a component of the
GPIb-V-IX complex on
platelets. The GPIb-V-IX complex binds
von Willebrand factor, allowing
platelet adhesion and
platelet plug formation at sites of vascular injury. Glycoprotein Ibα (GPIbα) is the major ligand-binding subunit of the GPIb-V-IX complex. GPIbα is heavily glycosylated.[2]
