Summaries for GALR2 Gene

Entrez Gene Summary for GALR2 Gene

  • Galanin is an important neuromodulator present in the brain, gastrointestinal system, and hypothalamopituitary axis. It is a 30-amino acid non-C-terminally amidated peptide that potently stimulates growth hormone secretion, inhibits cardiac vagal slowing of heart rate, abolishes sinus arrhythmia, and inhibits postprandial gastrointestinal motility. The actions of galanin are mediated through interaction with specific membrane receptors that are members of the 7-transmembrane family of G protein-coupled receptors. GALR2 interacts with the N-terminal residues of the galanin peptide. The primary signaling mechanism for GALR2 is through the phospholipase C/protein kinase C pathway (via Gq), in contrast to GALR1, which communicates its intracellular signal by inhibition of adenylyl cyclase through Gi. However, it has been demonstrated that GALR2 couples efficiently to both the Gq and Gi proteins to simultaneously activate 2 independent signal transduction pathways. [provided by RefSeq, Jul 2008]

GeneCards Summary for GALR2 Gene

GALR2 (Galanin 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 galanin receptor activity. An important paralog of this gene is SSTR2.

UniProtKB/Swiss-Prot for GALR2 Gene

  • Receptor for the hormone galanin and GALP. Receptor for the hormone spexin-1 (PubMed:24517231). The activity of this receptor is mediated by G proteins that activate the phospholipase C/protein kinase C pathway (via G(q)) and that inhibit adenylyl cyclase (via G(i)).

Tocris Summary for GALR2 Gene

  • Galanin is widely distributed in the central and peripheral nervous systems and the endocrine system. Three different galanin receptors (GAL1-3) have been identified which are Gi/o-protein-coupled. They are highly expressed in hypothalamic nuclei and the brainstem. In addition, they are found in proliferating zones of the fetal and adult brain and in peripheral tissues including the pancreas, heart, skin and gastrointestinal tract. Galanin receptors mediate a variety of physiological functions including inhibition of glucose-induced insulin secretion, stimulation of growth hormone release and modulation of gastrointestinal motility. These receptors also modulate neuronal functions including memory, nociception, spinal reflexes and feeding. Disruption of galanin expression or galanin receptor signaling is seen in many multifactoral conditions, suggesting a role in the development and/or pathology of certain diseases. These include Alzheimer's disease, epilepsy, diabetes, alcoholism, neuropathic pain and cancer.
