    Product Description

    P110 is a peptide inhibitor of the mitochondrial GTPase dynamin-related protein 1 (DRP1).1 It selectively inhibits DRP1 GTPase activity over the additional mitochondrial GTPases OPA1, MFN1, and dynamin 1 at 1 µM. P110 (1 µM) inhibits the MPP+-induced protein-protein interaction between DRP1 and mitochondrial fission 1 (FIS1), as well as MPP+-, carbonyl cyanide M-chloro phenyl hydrazone-, rotenone-, or hydrogen peroxide-induced DRP1 translocation to the mitochondria in SH-SY5Y cells. It also inhibits MPP+-induced mitochondrial apoptosis and autophagy in SH-SY5Y cells and MPP+-induced mitochondrial fragmentation and cell death in a primary rat dopaminergic neuronal model of Parkinson’s disease.

    WARNING This product is not for human or veterinary use.
