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.
