Delta Sleep-Inducing Peptide
Research context
DSIP is a nonapeptide originally isolated during work on sleep-related humoral factors. Research examines electroencephalographic delta activity in animal models, alongside receptor binding and stability characterisation. The literature is comparatively small and the receptor remains incompletely characterised.

Common questions
Is the DSIP receptor identified?
Not definitively. Despite the peptide being isolated decades ago, a specific receptor has not been conclusively characterised in the published literature — which is itself an active question in the field.
