ATAD3 proteins: brokers of a mitochondria–endoplasmic reticulum connection in mammalian cells

In yeast, a sequence of physical and genetic interactions termed the endoplasmic reticulum (ER)–mitochondria organizing network (ERMIONE) controls mitochondria–ER interactions and mitochondrial biogenesis. Several functions that characterize ERMIONE complexes are conserved in mammalian cells, suggesting that a similar tethering complex must exist in metazoans. Recent studies have identified a new family of nuclear‐encoded ATPases associated with...
