Abstract

Previous reports from our lab identified a mitochondrial calcium-independent phospholipase Ay activity that is activated when the mitochondrial membrane potential is decreased. This activity was demonstrated to influence occurrence of the permeability transition. Originally, this activity was ascribed to the iPLA(2)beta protein. Recently, both iPLA(2)beta and iPLA(2)gamma knock out mice have been generated. It has been shown by others that the iPLA(2)gamma plays a significant role in progression of the permeability transition. In this paper, using the iPLA(2)beta and iPLA(2)gamma knock out mice we show that the membrane potential sensitive activity is the iPLA(2)gamma. (C) 2015 Federation of European Biochemical Societies.
