Anti-SHIP1 Alexa Fluor® 647

SHIP-1 (SH2 domain containing inositol phosphatase-1) is a 5´inositol phosphatase that regulates cell responses in lymphocytes and myeloid cells by hydrolyzing the second messenger PI (3,4,5) trisphosphate. SHIP-1 is recruited upon engagement of both inhibitory and activatory receptors, such as FcgammaRIIB, Fcgamma RIII, FcepsilonRI or cytokine and growth factor receptors, and supresses PI3K-dependent signaling, down-regulates cell migration and invasion of transformed cells and phagocytosis. SHIP-1 also serves as a scaffold for the recruitment of other proteins to the plasma membrane.
