Naturally occurring calcium channels act as pores on the membranes of excitable cells, such as those found in nerves and ...

“So far, nobody has been able to identify the proteins involved in mediating this widely-expressed current,” said Jorg Grandl of Duke University in Durham, North Carolina, who was not involved in this ...

A member of an important class of ion channel proteins can transiently rearrange itself into a larger structure with dramatically altered properties, according to a study led by researchers at Weill ...

A novel method for studying how one crucial membrane protein functions may pave the way for a new kind of broad-spectrum antibiotic. Almost all bacteria rely on the same emergency valves -- protein ...

Almost all bacteria rely on the same emergency valves--protein channels that pop open under pressure, releasing a deluge of cell contents. It is a last-ditch effort, a failsafe that prevents bacteria ...

Strong interactions between lipids and proteins occur primarily through association of charged headgroups and amino acid side chains, rendering the protonation status of both partners important. Here ...

Estrogen, the major female ovarian hormone, can trigger nerve impulses within milliseconds to regulate a variety of physiological processes. At Baylor College of Medicine, Louisiana State University ...
