GPIba; GPIbalpha; GP-Ib alpha

Involved in blood coagulation and megakaryocyte development. Acts upstream of or within cell morphogenesis and hemostasis. Located in cell surface. Colocalizes with external side of plasma membrane. Is expressed in dorsal root ganglion; embryo; liver; and spinal cord. Used to study Bernard-Soulier syndrome. Human ortholog(s) of this gene implicated in Bernard-Soulier syndrome; Bernard-Soulier syndrome type A2; myocardial infarction; non-arteritic anterior ischemic optic neuropathy; and platelet-type bleeding disorder 3. Orthologous to human GP1BA (glycoprotein Ib platelet subunit alpha).
