Prostaglandin (PG) transporter SLCO2A1 plays an important role in the regulation of PG actions. Its loss of function is responsible for two refractory diseases, pachydermoperiostosis (PDP) and chronic enteropathy associated with SLCO2A1 (CEAS). We found that SLCO2A1 localizes differently at the plasma membrane and/or intracellular vesicles depending on the cell types. This differential localization modulates PG actions in opposite directions, "attenuated" and "enhanced," however the mechanisms of subcellular localization of SLCO2A1 remain unclear. In this study, we found that N-glycosylation, a post-translational modification, is one of the localization regulators that modulates the plasma membrane expression levels of SLCO2A1.
