GM-CSF receptor beta chain, Cytokine receptor common subunit beta, CDw131, GM-CSF/IL-3/IL-5 receptor common beta subunit, CSF2RB, IL3RB, IL5RB: GM-CSFr_.
GM-CSF Receptor Beta is the v 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. Six transcript variants encoding five different isoforms have been found for this gene, with some of the isoforms being membrane-bound and others being soluble.
