Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the endogenous pineal peptide epithalamin. It is characterized by its ability to modulate the activity of telomerase, an enzyme responsible for maintaining telomere length at the terminal ends of chromosomes. Epitalon functions as a potent epigenetic regulator, influencing chromatin structure and gene expression patterns associated with cellular senescence. Research applications include investigations into cellular longevity, DNA damage repair mechanisms, and the regulation of melatonin secretion and circadian rhythmicity.
