Mechanisms And Integration Of Signal Pathway: A Role For Calpains?, Dorothy E. Croall

University of Maine Office of Research Administration: Grant Reports

In order to survive cells must sense and respond to changes in their environment. Environmental cues trigger a variety of events within cells. The concentration and movements of calcium ions are essential regulators of many of these cellular responses. Proper control of intracellular calcium is essential because at thigh levels calcium can lead to cell damage or death. Calcium accomplishes it effects through binding to specific proteins such as calmodulin and calpain. Calmodulin, named for its ability to bind calcium and to modulate the activity of other cellular components, is an important mediator of calcium signals and its mechanism of …
