CD41, also known as integrin ?2b (ITGA2B), is a protein subunit of the heterodimeric integrin ?IIb?3 complex.{65453} It is composed of N-terminal extracellular ?-propeller, thigh, calf-1, and calf-2 domains, a transmembrane domain, and a C-terminal cytoplasmic domain.{65454} CD41 is expressed in platelets, as well as fetal hematopoietic stem and progenitor cells and a subtype of aging adult hematopoietic stem cells.{65455,65453} Signaling through the ?IIb?3 complex occurs via inside-out or outside-in mechanisms. Inside-out signaling occurs when a ligand binds and increases the affinity and avidity of the complex for ligands containing the Arg-Gly-Asp integrin recognition sequence, such as fibrinogen and von Willebrand factor, that are required for platelet aggregation and adhesion.{65455} Outside-in signaling of the ?IIb?3 complex regulates platelet spreading and plug formation and occurs due to integrin clustering or ligation and integration signaling from additional plasma membrane receptors. Various mutations in ITGA2B or ITGB3, the gene encoding CD61, the ?IIb?3 complex ?3 subunit, lead to a loss of ?IIb?3 expression and are associated with Glanzmann thrombasthenia, a coagulation disorder characterized by impaired clotting, abnormal bleeding, and bruising.{65454,65456} Cayman’s ITGA2B/CD41 Chimeric Monoclonal Antibody was produced recombinantly from the original 7E3 Fab antibody sequence and can be used for flow cytometry (FC). The 7E3 antibody was generated by immunization of mice with washed platelets, followed by fusion of the mouse spleen cells with a mouse myeloma cell line and subcloning.{65457,65458,65459}
