Description:Galanin is a neuropeptide that plays a significant role in various physiological processes, including the regulation of mood, appetite, and pain perception. The human form of galanin, identified by the CAS number 119418-04-1, is composed of a sequence of amino acids that allows it to interact with specific galanin receptors in the body. This interaction is crucial for mediating its effects on neurotransmission and hormonal regulation. Galanin is primarily expressed in the central nervous system and peripheral tissues, influencing functions such as neuroprotection, neurogenesis, and modulation of stress responses. It is also involved in the regulation of circadian rhythms and has been implicated in various pathological conditions, including depression and obesity. The peptide is characterized by its relatively small size and structural flexibility, which contribute to its ability to bind to multiple receptor subtypes. Overall, galanin serves as an important signaling molecule with diverse biological functions, making it a subject of interest in both basic and clinical research.
