Galanin is a widely distributed neuropeptide in the central nervous system, peripheral regions and endocrine system. Galanin has a role in energy homeostasis; central injections of galanin to the amygdala led to food intake in rats. Galanin also acts in the CNS to inhibit neurotransmitter release, such as acetylcholine. Galanin has been implicated in numerous neurological conditions, including Alzheimer’s disease, depression, and epilepsy.

Galanin interacts with 3 receptor subtypes, GalR1-3 G protein-coupled receptors inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway, but unlike GalR1, there is detectable inositol phosphate production. GalR3 is associated with the Gαi/o pathway. Activation of the receptor leads to a cellular influx of potassium ions.

The galanin active fragment 1-16 has been identified as a highly potent agonist for the galanin receptors.  These have become a basis for galanin-based peptides, which are neuroactive. These are being investigated as a potential source for anticonvulsant neuropeptides as a therapeutic for conditions such as epilepsy. A library of galanin fragments has allowed screening of their properties to be assessed and used to generate chimeric peptides. Galanin fragments have different affinities for GalR receptors; however, the N-terminal 1-16 have been shown to have a conserved affinity for the receptors. This galanin (2-13) peptide is provided in the acidic form. The amide form is also available in our catalogue.
