Abstract
The interaction of mitochondria with the endoplasmic reticulum (ER) Ca2+ store plays a key role in allowing these organelles to rapidly and effectively respond to cellular Ca2+ signals. In this contribution, we will briefly discuss: (i) old and new concepts of mitochondrial Ca2+ homeostasis; (ii) the relationship between mitochondrial 3D structure and Ca2+ homeostasis; (iii) the modulation by cytoplasmic signalling pathways; and (iv) new data suggesting that mitochondria and ER Ca2+ channels are assembled in a macromolecular complex in which the inositol-1,4,5-trisphosphate receptor directly stimulates the mitochondrial Ca2+ uptake machinery.Entities:
