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 CSF1Rgene (known also as c-FMS).[1][2] It is a receptor for a cytokine called colony stimulating factor 1.
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]
Another CSF1R inhibitor that targets/depletes TAMs is Cabiralizumab (cabira; FPA-008) which is a monoclonal antibody[13] and is in early clinical trials for metastatic pancreatic cancer.[14][15]
