Description

Introduction:

• Control of the mitochondrial ATP production by SR-derived Ca²⁺ signals includes local, nanodomain Ca²⁺ transfer from ryanodine receptors (RyR2) to the mitochondrial matrix (excitation-bioenergetics coupling).
• Ca²⁺ crosses the inner mitochondrial membrane (IMM) via the mtCU, a low-affinity Ca²⁺-activated Ca²⁺ channel complex.
• The surface area of cardiac IMM is extensively enhanced by cristae folding; however, mitoplast patch clamp studies showed mtCU current density the lowest amongst a range of tissues (Fieni 2012. Nat Commun).
