MGI Phenotype FUNCTION: This gene encodes a transmembrane protein located in the endoplasmic reticulum. The encoded protein is a receptor that binds several endogenous ligands, including N,N-dimethyltryptamine, progesterone and pregnenolone and a variety of of non-opiate compounds. The encoded protein plays a role in regulating the activity of ion channels, acting as a chaperone and protecting cells from oxidative stress. In humans, this receptor has been associated with Alzheimer's and Parkinson's diseases, stroke and numerous disease conditions such as depression, pain and addiction. Alternative splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq, Nov 2013]
PHENOTYPE: Mice homozygous for a gene trapped allele exhibit abnormal motor coordination and increased depressive-like behavior. Mice homozygous for a knock-out allele exhibit reduced sponataneous activity. [provided by MGI curators]
