A Lethal Channel between the ATP Synthase Monomers

Trends Biochem Sci. 2018 May;43(5):311-313. doi: 10.1016/j.tibs.2018.02.013. Epub 2018 Mar 16.

Abstract

The molecular structure of the transmembrane domain of ATP synthases is responsible for the inner mitochondrial membrane bending. According to the hypothesized mechanism, ATP synthase dissociation from dimers to monomers, triggered by Ca2+ binding to F1, allows the mitochondrial permeability transition pore formation at the interface between the detached monomers.

Keywords: ATP synthase; cristae; mitochondria; mitochondrial permeability transition pore.
