Comparison
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, SS-31 improves mitochondrial bioenergetics, reduces oxidative stress, and shows protective effects in models of ischemia-reperfusion, neurodegeneration, and other mitochondrial disorders4637137.
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, SS-31 is a mitochondria-targeted tetrapeptide, d-Arg-dimethylTyr-Lys-Phe-NH2, that selectively binds cardiolipin in the inner mitochondrial membrane, stabilizing cristae structure, improving electron transport, and reducing ROS production4637137143.
DSIP is 9 amino acids long, whereas SS-31 is shorter as it has a length of 4 amino acids. DSIP is made up of a sequence of Tryptophan, Alanine, Glycine, Glycine, Aspartic acid, Alanine, Serine, Glycine, Glutamic acid. SS-31 is made up of a sequence of Arginine, dimethylTyr, Lysine, Phenylalanine.
