Integrin alpha-2b (D8V7H) Rabbit Monoclonal Antibody #13807

Integrins are α/β heterodimeric cell surface receptors that play a pivotal role in cell adhesion and migration, as well as in growth and survival (1,2). The integrin family contains at least 18 α and 8 β subunits that form 24 known integrins with distinct tissue distribution and overlapping ligand specificities (3). Integrins not only transmit signals to cells in response to the extracellular environment (outside-in signaling), but also sense intracellular cues to alter their interaction with the extracellular environment (inside-out signaling) (1,2).
Integrin α2b is a cell-surface adhesion molecule that undergoes proteolytic cleavage to yield disulfide-linked heavy and light chains, which together with glycoprotein IIIb, forms a major fibrinogen receptor in activated platelets (3). Mutations in the corresponding ITGA2B gene can result in Glanzmann thrombasthenia, a bleeding disorder characterized by lack of platelet aggregation (4,5).
