UniprotKB: Accession Number Entry name Activity Subunit Subcellular location Cofactor
P36888 FLT3_HUMAN ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. Monomer in the absence of bound FLT3LG. Homodimer in the presence of bound FLT3LG. Interacts with FIZ1 following ligand activation (By similarity). Interacts with FES, FER, LYN, FGR, HCK, SRC and GRB2. Interacts with PTPRJ/DEP-1 and PTPN11/SHP2. Membrane, Single-pass type I membrane protein. Endoplasmic reticulum lumen. Note=Constitutively activated mutant forms with internal tandem duplications are less efficiently transported to the cell surface and a significant proportion is retained in an immature form in the endoplasmic reticulum lumen. The activated kinase is rapidly targeted for degradation.

Comments
This enzyme belongs to platelet-derived growth factor (PDGF) receptor family, along with homologous enzymes, such as colony-stimulating factor-1 receptor (CSF-1-R, cFMS) (M00330 in EzCatDB) and tyrosine-protein kinase Kit (Kit) (M00323 in EzCatDB).
The catalytic domain of this enzyme is homologous to that of vascular endothelial growth factor receptor (M00131 in EzCatDB).
