What Is DSIP?
Delta Sleep-Inducing Peptide (DSIP) is a synthetic nonapeptide consisting of nine amino acids. It was first isolated in 1977 from the cerebral venous blood of rabbits during experimentally induced sleep, which led to its name.
Its amino acid sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.
Although DSIP was originally investigated in connection with sleep-related physiological processes, its precise biological mechanisms remain incompletely understood. No dedicated DSIP receptor has been conclusively identified.
This makes DSIP a subject of ongoing laboratory research involving neuropeptide chemistry, receptor-ligand screening, molecular characterization and peptide stability.
