Calcium ions flow into the cells when animals and plants are exposed to influences such as bacterial attack, odour and cold. Though the calcium provides the cells with a signal about what is going on ...

Our cells are capable of moving energy and material around to the places where they are required, and ensuring that the body works properly. But how do the cells do this in real time from the ...

(Nanowerk News) The enzyme is the calcium-pumping Ca2+-ATPase - an ion pump protein that maintains a concentration of calcium inside the cell, which is about 20,000 times lower than outside. Only, it ...

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 ...

UK scientists have identified a new way to kill pancreatic cancer cells by 'pulling the plug' on the energy generator that fuels calcium pumps on their cell surface. The study, published in the ...

Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses. "We ...

Figure 1: CFTR chloride channel activity in CF-affected epithelial cells in control conditions or after treatment with thapsigargin. Figure 2: Effects of thapsigargin treatment on plasma membrane and ...

One of the cell's key enzymes, the calcium pump, has now been been described in its decisive moment -- a so-called transition state. These findings provide a very detailed picture of how one of the ...

The enzyme is the calcium-pumping Ca2+-ATPase - an ion pump protein that maintains a concentration of calcium inside the cell, which is about 20,000 times lower than outside. Only, it does not pump ...
