1. Protein Tyrosine Kinase/RTK
  2. c-Fms


c-FMS (CSF1R, CSF-1R) is a receptor protein-tyrosine kinase of the platelet-derived growth factor receptor (PDGFR) family. c-FMS is the cell surface receptor for IL-34 and CSF1. c-FMS has important roles in haematopoiesis, regulation of proliferation, cell survival and maturation of microglia and monocytes, as well as in controlling the overall immune response.

c-FMS is specifically expressed in osteoclasts and myelomonocytic-lineage cells, such as monocytes and macrophages, and the activation of c-FMS signaling promotes the proliferation or differentiation of these cells. It also promotes the production of inflammatory mediators, such as tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL6).
