Stable up to one year Product Description: PI4KIIB is a member of the phosphatidylinositol 4-kinase family (PI4K) that phosphorylate phosphatidylinositol to generate phosphatidylinositol 4-phosphate which are immediate precursor of several important signaling and scaffolding molecules. PI4KIIB is primarily a cytosolic PI4K that is recruited to membranes where it stimulates phosphatidylinositol 4,5-bisphosphate syntheses. PI4KIIB uses phosphatidylinositol as their primary substrate and has no activity on phosphatidylinositol monophosphates. PI4KIIB is a restricted minor histocompatibility antigen in patients that had been successfully treated with donor lymphocyte infusions for relapsed chronic myeloid leukemia after allogeneic stem cell transplantation.
