We searched for taste cell-expressed receptor transporting protein (RTP) and receptor expression enhancing protein (REEP) family members that might serve as accessory molecules to enhance gustatory receptor function. We determined that REEP2 is an integral membrane protein expressed in taste cells, physically associates with both subunits of the type 1 taste receptor 2 and type 1 taste receptor 3 sweet receptor and specifically enhances responses to tastants of heterologously expressed sweet and bitter taste receptors. Downregulation of endogenously expressed REEP2 in the chemosensory enteroendocrine GLUTag cell line dramatically reduced sensitivity of endogenous sweet receptors. In contrast to the observation that RTP1, RTP2, and REEP1 enhance function of olfactory receptors by promoting their transit to the cell surface, we found that REEP2 does not increase cell surface expression of sweet receptors but instead alters their spatial organization. REEP2 recruits sweet receptors into lipid raft microdomains localized near the taste cell's apical region, thereby improving G-protein-coupled receptor signaling and promoting receptor access to tastants arriving through the apical taste pore."xsd:string |
