In cell signaling, calcium is king. The flux of calcium ions across cell membranes regulates cellular activities from muscle contraction to neuron firing to immune cell function. A talk I saw here at ...

The endoplasmic reticulum (ER) is the portion of the cell responsible for manufacturing and folding proteins. Proteins are essential for a wide range of cellular functions—as enzymes, transporters, ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

A new method exposes key details of the mechanism behind calcium signaling in prokaryotes for the first time. Working in a Listeria monocytogenes model, researchers from Umeå University (Sweden) led ...

N-myristoylation on glycine is an irreversible modification that has long been recognized to govern protein localization and function. In contrast, the biological roles of lysine myristoylation remain ...

Taking Vitamin C and calcium together improves gut calcium absorption and may also enhance bone and immune system health.
