Colony stimulating factor 1 receptor (CSF1R), also known as macrophage colony-stimulating factor receptor (M-CSFR), and CD115 (Cluster of Differentiation 115), is a cell-surface protein encoded, in humans, by the CSF1R gene (known also as c-FMS).[1][2] It is a receptor for a cytokine called colony stimulating factor 1.
Genomics
The gene is located on long arm of chromosome 5 (5q32) on the Crick (minus) strand. It is 60.002 kilobases in length. The encoded protein has 972 amino acids and a predicted molecular weight of 107.984 kiloDaltons. The first intron of the CSF1R gene contains a transcriptionally inactive ribosomal protein L7 processed pseudogene, oriented in the opposite direction to the CSF1R gene.[1]
Function
The encoded protein is a single pass type I membrane protein and acts as the receptor for colony stimulating factor 1, a cytokine which controls the production, differentiation, and function of macrophages. This receptor mediates most, if not all, of the biological effects of this cytokine. Ligand binding activates CSF1R through a process of oligomerization and trans-phosphorylation. The encoded protein is a tyrosine kinase transmembrane receptor and member of the CSF1/PDGF receptor family of tyrosine-protein kinases.[3][4]
Clinical significance
Increased levels of CSF1R1 are found in microglia in Alzheimer's disease and after brain injuries. The increased receptor expression causes microglia to become more active.[5] Both CSF1R, and its ligand colony stimulating factor 1 play an important role in the development of the mammary gland and may be involved in the process of mammary gland carcinogenesis.[6][7][8]
Mutations in CSF1R are associated with chronic myelomonocytic leukemia and type M4 acute myeloblastic leukemia.[9]
Mutations in the tyrosine kinase domain have been associated with hereditary diffuse leukoencephalopathy with spheroids.
As a drug target
Because CSF1R is overexpressed in many cancers and on tumor-associated macrophages (TAM), CSF1R inhibitors (and CSF1 inhibitors) have been studied for many years as a possible treatment for cancer or inflammatory diseases.[10][11] As of 2017[update] CSF1R inhibitors in clinical trials include :[11] Pexidartinib, PLX7486, ARRY-382, JNJ-40346527,[12] BLZ945, Emactuzumab, AMG820, IMC-CS4. (PD-0360324 and MCS110 are CSF1 inhibitors)[13]
Another CSF1R inhibitor that targets/depletes TAMs is Cabiralizumab (cabira; FPA-008) which is a monoclonal antibody[14] and is in early clinical trials for metastatic pancreatic cancer.[15][16]
Interactions
Colony stimulating factor 1 receptor has been shown to interact with:
- Cbl gene,[17]
- FYN,[18]
- Grb2,[19]
- Suppressor of cytokine signaling 1,[20] This receptor is also linked with the cells of MPS.
