High-speed pumps: Cells use high-speed pumps to pump calcium ions out of their interior. A team has created the first comprehensive transport model of plasma membrane CaATPase (PMCA) to study calcium ...

Cells have to invest a lot of energy to maintain this concentration gradient, especially when it comes to getting rid of calcium. 'It's like being on a rush-hour train in a city like Tokyo. When the ...

Biochemists have uncovered the structure of cellular mechanism tied to thought, movement and other bodily functions. New atomic scale images of the structure of calcium's gatekeeper, IP3R, could go a ...

The process of energy generation by mitochondria is closely tied to intracellular calcium regulation by a membrane gateway inside mitochondria known as the mitochondrial Ca2+ uniporter (MCU). How MCU ...
