Description_x000D_ General description_x000D_ The gene ITGA2B (integrin subunit α 2b) encodes one of the 18 α subunits of integrins, which are transmembrane α/β heterodimers. The heterodimers, in mammals, are made up of a combination of one of 18 possible α subunits together with one of eight β subunits. The α and β subunits are type-I membrane proteins that contain a single transmembrane region linking a large extracellular domain and short noncatalytic cytoplasmic tail._x000D_ Immunogen_x000D_ human platelet membranes_x000D_ Application_x000D_ Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below._x000D_ Immunofluorescence (1 paper)_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Integrins function in various cellular processes, such as tissue migration during embryogenesis, cellular adhesion, cancer metastases, and lymphocyte helper and killer cell functions. The heterodimer αIIbβ3 functions primarily in platelet aggregation, a crucial process in hemostasis and thrombosis. Integrin αIIbβ3, also referred to as glycoprotein IIbIIIa is a major adhesion receptor on platelets that is capable of binding to fibrinogen upon platelet stimulation. Defects in this gene have been associated with Glanzmann thrombasthenia, an autosomal recessive bleeding disorder.
