FLT3(redirected from OTTHUMP00000214829)
FLT3A gene on chromosome 13q12 that encodes a class-III receptor tyrosine kinase, which regulates haematopoiesis. FLT3 is activated by binding 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 in turn phosphorylates and activates multiple cytoplasmic effectors involved in apoptosis, proliferation and differentiation of haematopoietic cells in bone marrow.
FLT3 mutations that activate the receptor are thought to induce acute (myeloid or lymphocytic) leukaemia.
