Gene type: protein coding
RefSeq status: VALIDATED
Organism: Rattus norvegicus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Also known as: GAL2-R; GALR-2
Summary: Enables galanin receptor activity and neuropeptide binding activity. Involved in several processes, including adenylate cyclase-activating G protein-coupled receptor signaling pathway; inositol phosphate metabolic process; and phosphatidylinositol metabolic process. Predicted to be located in cilium. Predicted to be active in plasma membrane. Orthologous to human GALR2 (galanin receptor 2). [provided by Alliance of Genome Resources, Dec 2024]
Annotation information: Note: In Rnor_6.0 (AR 105), the loci 29234 and 103690156 are placed twice on chromosome 10. This is likely an assembly error and not a true gene duplication. [28 May 2015]
Expression: Biased expression in Uterus (RPKM 41.1), Adrenal (RPKM 38.3) and 9 other tissues See more

PG early treatment prevented Y1R upregulation and resulted in lower NPY, Y2R and GalR1 mRNA levels. In the chronic phase, injured rats showed well-established mechanical and cold allodynia and significant increases in galanin, NPY, GalR1 and Y1R mRNAs, while maintaining reduced GalR2 expression. Animals receiving PG treatment showed basal expression levels of galanin, NPY, GalR1 and Y1R, and reduced Y2R mRNA levels

Results indicate that Galanin receptor 2/Neuropeptide Y Y1 receptor (GALR2/NPYY1R) interactions can provide a novel integrative mechanism in dentate gyrus in depression-related behavior and may give the basis for the development of drugs targeting GALR2/NPYY1R heteroreceptor complexes in the dentate gyrus of the hippocampus for the treatment of depression.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
