Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...

The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...

Calcium plays a central role in a diverse array of cellular processes including signal transduction, secretion of bioactive molecules, muscle contraction and gene expression. Over fifty years ago, it ...

Researchers have identified a previously unrecognized small protein in cells of the human heart that plays a key role in heart muscle contraction. The protein is made from an RNA that was previously ...

Muscles move our bodies. To do so, they contract, which then generates movement. Share on Pinterest Muscles use energy from our food to produce movement. Muscles allow us to consciously move our limbs ...
