The protein encoded by this gene is the alpha subunit of the heterodimeric receptor for colony stimulating factor 2, a cytokine which controls the production, differentiation, and function of granulocytes and macrophages. The encoded protein is a member of the cytokine family of receptors. This gene is found in the pseudoautosomal region (PAR) of the X and Y chromosomes. Multiple transcript variants encoding different isoforms have been found for this gene, with some of the isoforms being membrane-bound and others being soluble.,CSF2RA,CD116,CDw116,CSF2R,CSF2RAX,CSF2RAY,CSF2RX,CSF2RY,GM-CSF-R-alpha,GMCSFR,GMR,SMDP4,Immunology & Inflammation,CD markers,Cytokines,Cell Intrinsic Innate Immunity Signaling Pathway,Stem Cells,Mesenchymal Stem Cells,CSF2RA
