SS-31 (elamipretide) is a mitochondrially-targeted tetrapeptide that binds cardiolipin at the inner mitochondrial membrane in published research. Full Kiwi Peps profile inside.
The SS-31 peptide (also called elamipretide or MTP-131) is a mitochondrially-targeted tetrapeptide (D-Arg-2',6'-dimethylTyr-Lys-Phe-NH₂). Published in-vitro literature describes selective binding to cardiolipin at the inner mitochondrial membrane, stabilising respiratory-chain supercomplexes and reducing mitochondrial ROS in models of mitochondrial dysfunction.
