DSIP





DSIP
DSIP is a nonapeptide composed of the amino acid sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, recognized in research models for its sleep-supporting properties. Commonly used in studies focused on sleep regulation, circadian rhythm function, and neurological signalling involved in sleep-wake patterns. DSIP was originally isolated from the cerebral venous blood of rabbits during sleep-related research.

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide. It has been studied for its potential involvement in sleep regulation, stress response, and neuroprotective activity. DSIP and DSIP-like peptides have been reported in various regions of the nervous system and other tissues, although their precise physiological role remains under investigation.
DSIP has also been studied for its potential involvement in stress response, thermoregulation, and neuroendocrine processes. The peptide is composed of nine amino acids arranged in the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.
Current research applications include studies on:
- Sleep physiology
- Circadian rhythm biology
- Molecular pathways involved in regulating sleep and wakefulness
