Colony stimulating factor-1 (CSF-1) is the major regulator of tissue macrophage development and function. The effects of CSF-1 are mediated by the CSF-1 receptor (CSF-1R), a class III receptor tyrosine kinase belonging to the PDGF receptor family. To study CSF-1R structure/function in macrophages using both genetic and proteomic approaches, we developed a novel, CSF-1R-deficient, mouse bone marrow macrophage (BMM) line (MacCsf1r−/−) (
