Background: CSF1R is a tyrosine-protein kinase that acts as cell-surface receptor for CSF1 and IL34 and plays an essential role in the regulation of survival, proliferation and differentiation of hematopoietic precursor cells. CSF1-R also known as M-CSF, is a critical regulator of the development, morphology, survival, and functions of tissue macrophages and osteoclasts and plays an important role in innate immunity and in inflammatory processes. It is a transmembrane glycoprotein composed of an Ig-like extracellular ligand-binding domain, a hydrophobic transmembrane domain, and an intracellular C-terminal tyrosine kinase domain that includes eight tyrosine residues, known to be phosphorylated in the activated receptor. Upon activation by lingand binding intracellular autophosphorylated tyrosines behave as docking sites for a variety of proteins that include several Src family kinases, the p85 subunit of PI3K, phospholipase Cγ2, suppressor of cytokine signaling-1, Grb2, and c-Cbl.
