CSF1R / M-CSFR / CD115 Protein Description

M-CSFR encoded by the proto-oncogene c-fms is the receptor for colony stimulating factor 1, a cytokine involved in the proliferation, differentiation, and activation of macrophages. As a member of the typeIII subfamily of receptor tyrosine kinases (RTKs), M-CSF receptor is expressed mainly on cells of monocyte/macrophage lineage, and consists of an extracellular ligand-binding domain and a cytoplasmic protein tyrosine kinase (PTK) domain joined through a single transmembrane helix. Ligand binding induces the M-CSF receptor homodimerization, and leads to transphosphorylation of specific tyrosine and the subsequent signal transduction. This activated receptor exerts actions on multiple intracellular effectors which determine the magnitude and specificity of the biological responses, and thus mediates most if not all of the biological effects of the CSF1 cytokine, including cell growth, survival, differentiation and chemotaxis. Mutations of this gene have been associated with a predisposition to myeloid malignancy.
