Galanin/GALP Receptors and CNS Homeostatic Processes
Galanin is a 29/30 amino acid peptide neurotransmitter that is widely distributed throughout the central nervous system and periphery. There are three well-characterized G-protein coupled galanin receptors subtypes (GalR1-3). A more recently discovered 60 amino acid galanin-like peptide (GALP) shares amino acid sequence homology with galanin (1-13) in position 9-21 and has high binding affinity for GalR1-3, with highest affinity for GalR3. Considerable evidence has accumulated that implicates both galanin and GALP as playing important roles in regulating food and water intake behavior and related neuroendocrine functions. Pharmacological tools are emerging that will allow dissociation of specific roles for the peptides and their associated receptor subtypes in mediating the homeostatic processes of energy and fluid balance.

More about this publication?
- CNS & Neurological Disorders - Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular targets involved in neurological and central nervous system (CNS) disorders e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will contain a series of timely in-depth reviews written by leaders in the field covering a range of current topics on drug targets involved in neurological and CNS disorders. As the discovery, identification, characterization and validation of novel human drug targets for neurological and CNS drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
