FUNCTION: Orphan receptor. Could be a receptor fortrace amines.trace amines are biogenic amines present in very low levels in mammalian tissues. Although sometrace amines have clearly defined roles as neurotransmitters in invertebrates, the extent to which they function as true neurotransmitters in vertebrates has remained speculative.trace amines are likely to be involved in a variety of physiological functions that have yet to be fully understood. SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
