  "summary": "Mitochondria-associated endoplasmic reticulum (ER) membranes (MAM domains, or MAMs) are transient lipid raft domains of the ER that coordinate multiple cellular metabolic pathways and the ER-mitochondria communication. However, the mechanisms that drive their formation remain poorly understood. Here, we reveal that MAM assembly is dynamically regulated by the availability of plasma membrane (PM)…",
