The mitochondria-targeted tetrapeptide
SS-31 is a synthetic four-residue, mitochondria-targeted research peptide also described in literature as elamipretide. Its alternating aromatic and basic residues distinguish it from longer mitochondrial-derived peptides.
SS-31 is studied for its interaction with cardiolipin, a phospholipid concentrated in the inner mitochondrial membrane. This catalogue record describes the compound and its research context without making a use or outcome claim.
SS-31 appears in mitochondrial membrane, bioenergetics, and oxidative-stress research literature as a compact targeted tetrapeptide.
It is the research designation commonly used for the tetrapeptide also described as elamipretide.
Its alternating aromatic and basic residues are associated with selective interaction at the inner mitochondrial membrane.
