SS-31 is a mitochondria-targeting tetrapeptide that has been studied for its ability to selectively bind to cardiolipin, a phospholipid found in the inner mitochondrial membrane. By interacting with cardiolipin, SS-31 is thought to help stabilize mitochondrial structure and function, supporting cellular energy production.

In research models, SS-31 has been investigated for its potential roles in reducing oxidative stress, improving mitochondrial bioenergetics, and protecting cells from damage associated with aging, metabolic dysfunction, and ischemia-reperfusion injury. Its ability to cross mitochondrial membranes efficiently has made it a valuable tool in studying mitochondrial-targeted therapeutics.

Studies suggest that SS-31 may influence pathways related to cellular resilience, neuroprotection, and cardiovascular health, providing a unique approach for exploring mitochondrial biology in experimental settings.
