Multi-pass membrane protein {ECO:0000269|PubMed:27768894, ECO:0000269|PubMed:27851727}. Membrane raft {ECO:0000269|PubMed:21895628}. Mitochondrion outer membrane {ECO:0000250|UniProtKB:P47746}. Cell projection, axon {ECO:0000250|UniProtKB:P20272}. Presynapse {ECO:0000250|UniProtKB:P20272}. Note=Unexpectedly, in the mitochondria, the C-terminus is located in the mitochondrial intermembrane space, a compartment topologically considered as extracellular. In canonical seven-transmembrane G-protein coupled receptors, the C-terminus is cytosolic (By similarity). Found on presynaptic axon terminals in some GABAergic neurons in the somatosensory cortex (By similarity). {ECO:0000250|UniProtKB:P20272, ECO:0000250|UniProtKB:P47746}.
