CC -!- FUNCTION: Alpha-2 adrenergic receptors mediate the catecholamine-
CC induced inhibition of adenylate cyclase through the action of G
CC proteins. Component of the ATAC complex, a complex with histone
CC acetyltransferase activity on histones H3 and H4 (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Component of the ADA2A-containing complex (ATAC), composed of
CC KAT14, KAT2A, TADA2L, TADA3L, ZZ3, MBIP, WDR5, YEATS2, CCDC101 and DR1.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC Adrenergic receptor subfamily. ADRA2A sub-subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
CC -!- CAUTION: It is uncertain whether Met-1 or Met-15 is the initiator.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAA67074.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
