Abstract |
Granulocyte colony-stimulating factor (G-CSF) receptor (G-CSFR) is a type I cytokine receptor which is involved in hematopoietic cell maturation. G-CSFR has three putative C-mannosylation sites at W253, W318, and W446; however, it is not elucidated whether G-CSFR is C-mannosylated or not. In this study, we first demonstrated that G-CSFR was C-mannosylated at only W318. We also revealed that C-mannosylation of G-CSFR affects G-CSF-dependent downstream signaling through changing ligand binding capability but not cell surface localization. Moreover, C-mannosylation of G-CSFR was functional and regulated granulocytic differentiation in myeloid 32D cells. In conclusion, we found that G-CSFR is C-mannosylated at W318 and that this C-mannosylation has role(s) for myeloid cell differentiation through regulating downstream signaling.
