SS-31, also designated elamipretide or MTP-131, is a synthetic mitochondria-targeting tetrapeptide of the Szeto-Schiller peptide class. In laboratory research, the SS-31 peptide is studied for its selective association with cardiolipin, a phospholipid concentrated in the inner mitochondrial membrane, and as a tool compound in models of mitochondrial bioenergetics and oxidative-stress signaling.
Because of its aromatic-cationic structure, SS-31 partitions into the inner mitochondrial membrane largely independent of membrane potential, which has made it a frequent reference compound in preclinical investigations of mitochondrial membrane biology.
Preclinical investigations have explored SS-31 in experimental models studying:
Experimental research examines SS-31 through its interaction with cardiolipin in the inner mitochondrial membrane, with downstream effects studied across several bioenergetic pathways.
Areas of investigation include:
These mechanisms are commonly studied in isolated mitochondria and cellular models of energy metabolism.
