CC -!- FUNCTION: Tyrosine-protein kinase that acts as cell-surface receptor
CC for the cytokine kitlg/scf and plays an essential role in the
CC regulation of cell survival and proliferation, hematopoiesis, stem cell
CC maintenance, gametogenesis, mast cell development, migration and
CC function, and in melanogenesis. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-tyrosyl-[protein] = ADP + H(+) + O-phospho-L-tyrosyl-
CC [protein]; Xref=Rhea:RHEA:10596, Rhea:RHEA-COMP:10136, Rhea:RHEA-

CC ChEBI:CHEBI:82620, ChEBI:CHEBI:456216; EC=2.7.10.1;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10028};
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass type I
CC membrane protein {ECO:0000250}.
CC -!- PTM: Ubiquitinated. Rapidly ubiquitinated after autophosphorylation
CC induced by kitlg/scf binding, leading to internalization and
CC degradation. {ECO:0000250}.
CC -!- PTM: Autophosphorylated on tyrosine residues. Phosphorylated tyrosine
CC residues are important for interaction with specific binding partners
CC (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
CC kinase family. CSF-1/PDGF receptor subfamily. {ECO:0000255|PROSITE-
CC ProRule:PRU00159}.
