CC -!- FUNCTION: Tyrosine-protein kinase that acts as a cell-surface receptor
CC for CSF1 and plays an essential role in the regulation of survival,
CC proliferation and differentiation of hematopoietic precursor cells,
CC especially mononuclear phagocytes, such as macrophages and monocytes.
CC Plays an important role in innate immunity and in inflammatory
CC processes. Plays an important role in the regulation of osteoclast
CC proliferation and differentiation, the regulation of bone resorption,
CC and is required for normal bone development. Promotes reorganization of
CC the actin cytoskeleton, regulates formation of membrane ruffles, cell
CC adhesion and cell migration. Activates several signaling pathways in
CC response to ligand binding. {ECO:0000256|ARBA:ARBA00058066}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-tyrosyl-[protein] + ATP = O-phospho-L-tyrosyl-[protein] +
CC ADP + H(+); Xref=Rhea:RHEA:10596, Rhea:RHEA-COMP:10136, Rhea:RHEA-
