Membrane contact sites play a critical role in intercompartmental communication. This article presents a protocol for engineering and validating a synthetic bridge between the inner and outer mitochondrial membranes to support the functioning of the MICOS complex. The use of this approach provides valuable insights into the function of MICOS and associated proteins.
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 the mitochondrial membranes. This approach can be a valuable tool to study the function of the MICOS complex and associated proteins. For complete details on the use and execution of this protocol, please refer to Viana et al. (2021).
