Phosphatidylinositol 3,4,5-trisphosphate-dependent guanine nucleotide exchange factor (GEF) which, independently of RAS, transduces signals from tyrosine kinase receptors to RAC. It also mediates signaling of membrane ruffling. Regulates the actin cytoskeleton as an effector or adapter protein in response to agonist stimulated phosphatidylinositol (3,4)-bisphosphate production and cell protrusion.
Specificity
Natural and recombinant Bovine Switch-associated protein 70
Subcellular Location
Cytoplasm Cell membrane Nucleus Cell projection lamellipodium In resting B-cells it is localized mainly in the cytoplasm and upon cell activation it is recruited to the plasma membrane and then translocates to the nucleus. In activated, class-switching B-cells it is associated with membrane IgG but not IgM. Localized to loose actin filament arrays located behind actively extending lamellipodia.
