Abstract

Membrane contact sites are recognized as critical means of intercompartmental communication. Here, we describe a protocol for engineering and validating a synthetic bridge between the inner and outer mitochondrial membranes to support functioning of the endogenous mitochondrial contact site and cristae organizing system (MICOS). A chimeric protein,MitoT, is stably expressed in cultured mammalian cells to bridge themitochondrial membranes. This approach can be a valuable tool to study the function of the MICOS complex and associated proteins.
