SS-31
SS-31
SS-31 is a mitochondria-targeting tetrapeptide studied for its interaction with cardiolipin, a phospholipid located within the inner mitochondrial membrane. Laboratory research involving SS-31 examines peptide interactions with mitochondrial structures and associated cellular signaling systems. Experimental models explore mitochondrial membrane dynamics, peptide-lipid interactions, and biological pathways related to mitochondrial signaling processes. These investigations contribute to broad scientific research focused on mitochondrial structure and peptide-mediated cellular communication systems. SS-31 continues to be investigated in laboratory environments studying mitochondrial signaling pathways.
