DSIP has been described as a sleep-promoting substance. There is a modulating effect on sleep and wake functions with a greater activity in circumstances where sleep is disturbed. There are minimal effects in healthy subjects who are not suffering from sleep disturbance.
Delta sleep-inducing peptide, abbreviated DSIP, is a neuropeptide that when infused into the mesodiencephalic ventricle of recipient rabbits induces spindle and delta EEG activity and reduced motor activities.
Its aminoacid sequence is TRP-ALA-GLY-GLY-ASP-ALA-SER-GLY-GLU However, the gene is unknown[citation needed], raising serious questions regarding the actual existence of this peptide in nature.

DSIP Delta Sleep Inducing Peptide Benefits
Roles in endocrine regulation
Decreases basal corticotropin level and blocks its release
Stimulates release of luteinizing-hormone (LH)
Stimulates release of somatoliberin and somatotrophin secretion and inhibits somatostatin secretion.
Roles in physiological processes
Can act as a stress limiting factor.

May have a direct or indirect effect on body temperature and alleviating hypothermia.
Can normalize blood pressure and myocardial contraction.
It has been shown to enhance the efficiency of oxidative in rat mitochondria in vitro, suggesting it may have antioxidant effects.
There is also conflicting evidence as to its involvement in sleep patterns. Some studies suggest a link between DSIP and slow-wave sleep (SWS) promotion and suppression of paradoxical sleep, (PS)while some studies show no correlation.Stronger effects on sleep have been noted for the synthesized analogues of DSIP.
