Human FLT3, C-terminal fragment, amino acids R571-S993 (as in NCBI/Protein entry NP_004110.2), internal tandem duplication(oncological mutation: ITD) of aa 591-600 N-terminal GST-HIS6 fusion protein with a 3C cleavage site, was expressed in Sf9 insect cells
This gene encodes a class III receptor tyrosine kinase that regulates hematopoiesis. This receptor is activated by binding of the fms-related tyrosine kinase 3 ligand to the extracellular domain, which induces homodimer formation in the plasma membrane leading to autophosphorylation of the receptor. The activated receptor kinase subsequently phosphorylates and activates multiple cytoplasmic effector molecules in pathways involved in apoptosis, proliferation, and differentiation of hematopoietic cells in bone marrow. Mutations that result in the constitutive activation of this receptor result in acute myeloid leukemia and acute lymphoblastic leukemia.
