Research profile

SS-31 is a research peptide used in preclinical laboratory models involving metabolic, mitochondrial, or immune pathways.

What is it?

SS-31 is a synthetic tetrapeptide developed for investigational and in vitro research use, designed to selectively associate with cardiolipin-rich regions of the inner mitochondrial membrane. Its structure enables targeted interaction with mitochondrial components involved in electron transport and oxidative signaling.

In preclinical and laboratory research models, SS-31 has been studied for its influence on mitochondrial efficiency, reactive oxygen species modulation, and cellular energy signaling pathways. These properties have made it a compound of interest in experimental studies examining mitochondrial resilience, metabolic stress response, and cardiomyocyte energy dynamics.

Mechanism of Interest

Cardiolipin Binding — Studied for selective association with cardiolipin in the inner mitochondrial membrane.
Electron Transport — Examined in models of oxidative phosphorylation and mitochondrial efficiency.
Reactive Oxygen Species — Evaluated for modulation of oxidative signaling in cellular models.

Key Research Applications

Mitochondrial bioenergetics research
Oxidative stress pathway modeling
Cardiomyocyte energy dynamics studies
