RT receptor.";

CC -!- FUNCTION: Dopamine receptor whose activity is mediated by G proteins
CC which inhibit adenylyl cyclase (PubMed:11054572). Positively regulates
CC postnatal regression of retinal hyaloid vessels via suppression of
CC VEGFR2/KDR activity, downstream of OPN5 (By similarity).
CC {ECO:0000250|UniProtKB:P61168, ECO:0000269|PubMed:11054572}.
CC -!- SUBUNIT: Forms homo- and heterooligomers with DRD4. The interaction
CC with DRD4 may modulate agonist-induced downstream signaling. Interacts
CC with CADPS and CADPS2 (By similarity). Interacts with GPRASP1, PPP1R9B
CC and CLIC6. Interacts with ARRB2 (By similarity). Interacts with HTR2A
CC (By similarity). Interacts with DRD1. Interacts with KCNA2 (By
CC similarity). {ECO:0000250|UniProtKB:P14416,
CC ECO:0000250|UniProtKB:P61168, ECO:0000250|UniProtKB:P61169}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P14416};
CC Multi-pass membrane protein {ECO:0000255}. Golgi apparatus membrane
CC {ECO:0000250|UniProtKB:P14416}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- PTM: Palmitoylated. Palmitoylation which is required for proper
CC localization to the plasma membrane and stability of the receptor could
CC be carried on by ZDHHC4, ZDHHC3 and ZDHHC8.
CC {ECO:0000250|UniProtKB:P14416}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
