FMS-Like Tyrosine Kinase-3
Receptor tyrosine kinases are cell surface receptors that transduce signals mainly from extracellular stimuli leading to activation of numerous intracellular signaling cascades. The human genome encodes 58 receptor tyrosine kinases which can be subdivided into 20 different families (Lemmon and Schlessinger 2010). Within the 20 different families, the type III receptor tyrosine kinase family, also known as PDGFR family, consists of five receptor tyrosine kinases including PDGFRA, PDGFRB, KIT, CSF1R, and FLT3. The Fms-like tyrosine kinase 3 (FLT3) is a receptor for the dimeric FLT3 ligand (FL). The receptor was first described by two different groups in human and mouse (Matthews et al. 1991; Rosnet and Marchetto. 1991; Rosnet et al. 1991). In human, it was mapped to chromosome 13q12 and in mouse it was mapped to chromosome 5.
