Calcium (Ca2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum ...

Calcium signalling represents a fundamental process in cellular communication, orchestrating diverse physiological responses from muscle contraction to neurotransmission and gene regulation. At the ...

To acquire an image of calcium signaling, Reto Fiolka, a cell biologist at the University of Texas Southwestern Medical Center, illuminated primary cortical neurons from embryonic rats with three ...

Glycine, a non-essential amino acid derived from serine, plays an increasingly recognized role in metabolic regulation. Epidemiological studies ...

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 ...

Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...

Stone cells arise from lignified secondary cell walls and cause a gritty texture, reduced sweetness, and poor flavor in many ...

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in memory. CaMKII alters the plasma membrane's biochemical properties, ...

NEW YORK (Reuters Health) - In elderly people, higher levels of calcium in the blood are associated with poorer mental function and faster decline in cognitive ability, Dutch researchers have shown.

Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store. When plants are infected by pathogens, suffer from a lack of water or ...
