English The Ca²⁺-binding proteins parvalbumin (PV) and calbindin D-28k (CB) are key players in the intracellular Ca²⁺-buffering in specific cells including neurons and have profound effects on spatiotemporal aspects of Ca²⁺ transients. The previously observed increase in mitochondrial volume density in fast-twitch muscle of PV−/− mice is viewed as a specific compensation mechanism to maintain Ca²⁺... Show more…
