CSFR (human)

CSFR an oncogenic tyrosine kinase receptor for CSF-1 (M-CSF). Drives growth and development of monocytes. Binding of CSF-1 induces receptor dimerization, activation and autophosphorylation of cytoplasmic tyrosine residues used as docking sites for SH2-containing signaling proteins. There are at least five major tyrosine autophosphorylation sites. Two point mutations seen in 10-20% of patients with acute myeloid leukemia, chronic myelomonocytic leukemia or myelodysplasia. One mutation appears to be both somatic and germline, and disrupts Cbl binding and receptor turnover. v-fms lacks the Cbl binding site and causes feline leukemia. Mutations may also develop after chemotherapy for lymphoma. A distinct point mutation was found in some cases of hepatocellular carcinoma and related to increased expression, and another mutation was found in 2 of 40 patients with idiopathic myelofibrosis. Expression is elevated in breast tumors and cell lines, and expression in xenografts and transgenic mice has been correlated with xenograft growth and breast cancer development. Inhibitors: Ki-20227 and other Kit/PDGFR inhibitors. Note: This description may include information from UniProtKB.
