FLT3 - fms related receptor tyrosine kinase 3 Gene
Also Known as FLK2; STK1; CD135; FLK-2
Species: Homo sapiens
About FLT3
This gene has 3 transcripts (splice variants), 134 orthologues, 53 paralogues and is associated with 140 phenotypes. Broad expression in spleen (RPKM 4.2), lymph node (RPKM 3.7) and 16 other tissues.
Summary
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. [provided by RefSeq, Jan 2015]
