a receptor tyrosine kinase of the PDGFR family that binds the FL cytokine. FLT3 -/- mice have an impaired developmental capacity of primitive hematopoietic progenitor cells of all lineages with the greatest impact on lymphopoietic precursors. Activating mutations found in one third of cases of acute myeloid leukemia (AML), as well as in acute lymphoblastic leukemia, acute promyelocytic leukemia and myelodysplastic syndrome. Inhibitors: Sutent and PKC412. Note: This description may include information from UniProtKB.
