Calcium signal propagation from endoplasmic reticulum (ER) to mitochondria regulates a multitude of mitochondrial and cell functions, including oxidative ATP production and cell fate decisions. Ca 2+ transfer is optimal at the ER-mitochondrial contac

The formation and dissolution of ER-Mitochondria contacts is unclear. Here, authors show that the IP3 receptor traffics in and out of the contacts and, when trapped, improves calcium signaling to stimulate energy metabolism.

Membrane contact sites between the ER and mitochondria are known to convey calcium signals between these two organelles via IP3 receptors, but the molecular mechanisms are currently unclear. Here, the authors show that IP3 receptors play a structural

Summary: This study shows that multiple modes of mitochondrial stress generated by partial mtDNA depletion or cytochrome c oxidase disruption cause ryanodine receptor channel (RyR) dysregulation, which instigates the release of Ca2+ in the cytoplasm

Mitochondrial Ca2+ uptake through the Ca2+ uniporter supports cell functions, including oxidative metabolism, while meeting tissue-specific calcium signaling patterns and energy needs. The molecular mechanisms underlying tissue-specific control of th

Background: Cardiac contractile function requires high energy from mitochondria, and Ca 2+ from the sarcoplasmic reticulum (SR). Via local Ca 2+ transfer at close mitochondria-SR contacts, cardiac excitation feedforward regulates mitochondrial ATP pr

Mitochondrial calcium uptake is a highly regulated process, and calcium overload can lead to cell death. Here, using knockout mouse model, the authors show that the mitochondrial calcium uniporter (MCU) regulator MICU1 is needed to prevent calcium ov

In a physiological setting, mitochondria increase oxidative phosphorylation during periods of stress to meet increased metabolic demand. This in part is mediated via enhanced mitochondrial Ca2+ uptake, an important regulator of cellular ATP homeostas

Summary: Mitochondrial Ca2+ elevations enhance ATP production, but uptake must be balanced by efflux to avoid overload. Uptake is mediated by the mitochondrial Ca2+ uniporter channel complex (MCUC), and extrusion is controlled largely by the Na+/Ca2+
