Large-conductance calcium-activated potassium (BK) channels are critical determinants of smooth muscle function by mediating rapid feedback between intracellular calcium levels and membrane potential.

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 ...

New mechanism found: Researchers discovered that statins can bind to and activate ryanodine receptors in muscle cells, potentially explaining muscle pain in some patients. Why it matters: Uncovering ...
