  • Source
    Human ITGAIIb&ITGB3 Heterodimer Protein, His Tag&Tag Free(IT3-H52W8) is expressed from human 293 cells (HEK293). It contains AA Leu 32 - Arg 993 (ITGAIIb) & Gly 27 - Asp 718 (ITGB3) (Accession # P08514-1 (ITGAIIb) & P05106-1 (ITGB3)).
    Predicted N-terminus: Leu 32 (ITGAIIb) & Gly 27 (ITGB3)
  • Molecular Characterization
    Integrin alpha 2b beta 3 Structure

    Human ITGAIIb&ITGB3 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGAIIb and ITGB3, has a calculated MW of 111.4 kDa (ITGAIIb) and 81.8 kDa (ITGB3). Subunit ITGAIIb is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB3 contains no tag but a basic tail at the C-terminus. The non-reducing (NR) protein migrates as 115-130 kDa (ITGAIIb) and 85-92 kDa (ITGB3) respectively due to glycosylation.

  • Background
    Integrin alpha IIb beta 3 exist in a conformational equilibrium clustered around four main states. These conformations range from a compact bent nodule to two partially extended intermediate conformers and finally to a fully upright state. Activation of blood platelets by physiological stimuli at sites of vascular injury induces inside-out signaling, resulting in a conformational change of the prototype Integrin alpha IIb beta 3 from an inactive to an active state competent to bind soluble fibrinogen. Furthermore, ligand occupancy of Integrin alpha IIb beta 3 outside-in signaling and additional conformational changes of the receptor, leading to the exposure of extracellular neoepitopes termed ligand-induced binding sites (LIBS), which are recognized by anti-LIBS monoclonal antibodies.
