FMS-related tyrosine kinase 3 (FLT3, also called Flk2), a member of the type III receptor tyrosine kinase family that includes c-Kit, PDGF and M-CSF receptors, is expressed on early hematopoietic progenitor cells, and supports growth and differentiation within the hematopoietic system. FLT3 is activated after binding with its ligand FL, which results in a cascade of tyrosine autophosphorylation and tyrosine phosphorylation of downstream cellular targets. The p85 subunit of PI3 kinase, SHP2, GRB2 and Shc are associated with FLT3 after FL stimulation. Tyrosine 591 is located in the juxtamembrane region of FLT3. It may play an important role in regulation of FLT3 tyrosine kinase activity. Somatic mutations of FLT3 consisting of internal tandem duplications (ITDs) occur in 20% of patients with acute myeloid leukemia.
