gar-2 encodes a novel, seven transmembrane-domain G protein-coupled acetylcholine receptor (AChR); when expressed in Xenopus oocytes treated with acetylcholine, GAR-2 is able to activate a mammalian G protein-activated inwardly rectifying K+ (GIRK1) channel, but not other channels, suggesting that GAR-2 couples to G proteins of the Gi family; pharmacological analyses indicate, however, that GAR-2 exhibits properties distinct from mammalian muscarinic AChRs; gar-2 is expressed from mid-embryogenesis through adulthood with expression seen in ciliated head neurons, ventral cord neurons, and the HSN (hermaphrodite-specific neuron).
Enables G protein-coupled acetylcholine receptor activity. Involved in G protein-coupled receptor signaling pathway; negative regulation of cholinergic synaptic transmission; and response to xenobiotic stimulus. Located in axon. Expressed in neurons.
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
