DSIP is a linear nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu and a molecular weight near 849 daltons, first characterized in 1977, supplied as 4mg of lyophilized powder.
NeuropeptidesOverview
DSIP is a nine-residue peptide containing no cysteine and therefore no disulfide bridge. Its sequence includes two acidic residues (Asp5 and Glu9) and a single N-terminal tryptophan, giving the molecule an acidic isoelectric point. No cognate receptor has been identified.
Reported molecular interactions are diffuse rather than tied to a single binding site and include corticotropin-releasing hormone signaling and opioid receptor pathways in cell-free and cultured-cell systems. The peptide is hydrolyzed rapidly by peptidases in vitro, and the lyophilized solid dissolves in water.
Mechanism of Action
No cognate DSIP receptor has been characterized; reported activity is distributed across corticotropin-releasing hormone signaling and opioid receptor pathways in cultured-cell systems, with no single high-affinity binding site established.
