G protein-linked effector and second messenger systems involved in melatonin signal transduction

David C New et al. Neurosignals. 2003 Mar-Apr.

Abstract

The isolation and characterization of multiple melatonin receptors in a wide range of tissues and cells signifies the functional diversity of melatonin. In different cellular environments, melatonin can regulate distinct second messengers or even positively or negatively regulate the same signal transduction pathway. The capacity by which melatonin receptors modulate the activities of various effector molecules is determined by the complement of signaling components present in any particular cell type. The specific interactions between many signaling molecules have been discerned in an increasing number of cellular systems and this information is being used to explain the physiological actions of melatonin. This review will attempt to summarize recent research by many groups that has revealed numerous subtleties of the melatonin-coupled signaling pathways.
