Alomone Labs human Galanin activates Galanin 2 receptor-mediated Ca2+ mobilization in CHO-K1-Gα16-mt Aequorin cells.Dose response of normalized activation of the Galanin 2 receptor-mediated Ca2+ mobilization, evoked by human Galanin (#GPG-050). Ca2+ response was detected by measuring aequorin-derived fluorescence following application of human Galanin at different concentrations. The EC50 measured for human Galanin is 5.76 nM.
Galanin is a peptide hormone that acts as a non-selective and potent galanin receptor agonist. In human, Galanin is a C-terminal-amidated 30-residue peptide deriving its name from the N-terminal glycine and C-terminal alanine residue1,2. Galanin receptors belong to the family of G-protein coupled receptors and consist of three subtypes: GalR1, GalR2, and GalR3.
Galanin is widely distributed through the central and peripheral nervous system and its biological activity includes contraction or relaxation of gut smooth muscles, inhibition of insulin and somatostatin release, and modulation of hormone secretion from the pituitary and adrenal glands. It is believed that galanin plays an important role as a neuromodulator of endocrine secretion and synaptic transmission1. Additional studies show that galanin and its receptors are involved in the transmission and modulation of nociception of the central nervous system, at spinal cord levels and in the brain2.
