This gene encodes a member of a subfamily of G-protein-coupled neuropeptide receptors. This protein is activated by the neuropeptides A-18-amide (NPAF) and F-8-amide (NPFF) and may function in pain modulation and regulation of the opioid system. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2009]
GeneCards Summary for NPFFR2 Gene
NPFFR2 (Neuropeptide FF Receptor 2) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include G-protein coupled receptor activity and opioid receptor binding. An important paralog of this gene is NPFFR1.
UniProtKB/Swiss-Prot for NPFFR2 Gene
Receptor for NPAF (A-18-F-amide) and NPFF (F-8-F-amide) neuropeptides, also known as morphine-modulating peptides. Can also be activated by a variety of naturally occurring or synthetic FMRF-amide like ligands. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system
Neuropeptide FF/AF (NPFF) receptors are a group of Gi/Go-protein coupled receptors that are divided into two subtypes; NPFF1 and NPFF2. NPFF receptors act through inhibition of adenylyl cyclase and activation of phospholipase C and are coupled to voltage-gated N-type calcium channels. NPFF receptors have been implicated in hormonal modulation, regulation of food intake, thermoregulation and nociception through modulation of the opioid system. NPFF receptors are distributed across the central nervous system, but each subtype has specific localizations. NPFF1 are found in their highest concentrations in the septum, nucleus of the tractus solitarius and hypothalamus, suggesting their participation in neuroendocrine functions. NPFF2 are found in their highest concentrations in the diencephalon and superficial layers of the spinal cord, suggesting their participation in the modulation of pain. The human genes encoding NPFF1 and NPFF2 receptors are located on chromosomes 4q21 and 10q21-22 respectively.
