DESCRIPTION

Also known as RTP4_HUMAN, RTP4, IFRG28, Z3CXXC4. Probable chaperone protein which facilitates trafficking and functional cell surface expression of some G-protein coupled receptors (GPCRs). Promotes functional expression of the bitter taste receptor TAS2R16 (PubMed:16720576). Also promotes functional expression of the opioid receptor heterodimer OPRD1-OPRM1 (By similarity). Interacts with TASR16 (PubMed:16720576). Interacts with OPRD1 and OPRM1; the interaction promotes cell surface localization of the OPDR1-OPRM1 heterodimer (By similarity).
