Comparison

DSIP vs Dulaglutide

Function

While DSIP was originally described for inducing spindle and delta sleep activity when infused into the brain of rabbits; later studies report stress-modulating and endocrine effects, though its physiological role is still debated47, Dulaglutide is a once-weekly GLP-1RA for type 2 diabetes that lowers HbA1c and body weight by enhancing glucose-dependent insulin secretion and reducing appetite6668.

Mechanism

While DSIP works as an endogenous nonapeptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with proposed neuromodulatory actions; it interacts with components of the MAPK cascade and may be related to glucocorticoid-induced leucine zipper (GILZ), but its precise biosynthetic origin remains unknown4757, Dulaglutide is a recombinant fusion protein consisting of two disulfide-linked GLP-1(7–37) analogs each covalently fused via a linker to an IgG4 Fc fragment, yielding a large, long-acting GLP-1 receptor agonist protected from DPP-4 degradation66.

Length and Sequence

DSIP is 9 amino acids long, whereas Dulaglutide is shorter as it has a length of amino acids. DSIP is made up of a sequence of Tryptophan, Alanine, Glycine, Glycine, Aspartic acid, Alanine, Serine, Glycine, Glutamic acid. Dulaglutide is made up of a sequence of sequence data not available in the current dataset.
