RT "Cloning and expression of a full-length transcript for the equine
RT adenosine A2A receptor.";
RL Submitted (SEP-2003) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Receptor for adenosine (By similarity). The activity of this
CC receptor is mediated by G proteins which activate adenylyl cyclase (By
CC similarity). {ECO:0000250|UniProtKB:P11617}.
CC -!- SUBUNIT: Interacts (via cytoplasmic C-terminal domain) with USP4; the
CC interaction is direct (By similarity). May interact with DRD4 (By
CC similarity). Interacts with NECAB2 (By similarity). Interacts (via
CC cytoplasmic C-terminal domain) with GAS2L2; interaction enhances
CC receptor-mediated adenylyl cyclase activity (By similarity).
CC {ECO:0000250|UniProtKB:P29274, ECO:0000250|UniProtKB:P30543}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P30543};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:P30543}.
CC Note=Colocalizes with GAS2L2 at neuronal processes.
CC {ECO:0000250|UniProtKB:P30543}.
CC -!- DOMAIN: The cytoplasmic C-terminal domain is necessary for targeting
CC the non-ubiquitinated form of this protein to the cell surface.
CC {ECO:0000250}.
CC -!- PTM: Ubiquitinated. Deubiquitinated by USP4; leading to stabilization
CC and expression at the cell surface (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
