A non-canonical unfolded protein response pathway and mitochondrial dynamics control the number of ER-mitochondria contact sites

R. Kojima, Y. Kakimoto, M. Shinmyo, K. Kurokawa, A. Nakano, T. Endo, Y. Tamura

This study identifies a novel role of mitochondrial dynamics in regulating ER-mitochondria contact sites in yeast, showing that ER stress affects ERMES cluster stability independently of the canonical UPR pathway.
