The type 1 ryanodine receptor (RyR1) is an important calcium release channel in skeletal muscles essential for muscle contraction. It mediates calcium release from the sarcoplasmic reticulum, a ...

Genetic model reveals a form of calcium release is unnecessary for normal muscle contraction
The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...
The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...
The pumping action of the calcium pump protein—an intricate molecular machine with several moving parts that helps control muscle contraction—has been detailed with exquisite precision by RIKEN ...
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 ...
Ferulic acid suppresses ileal smooth muscle contraction by inhibiting calcium ion influx through voltage-dependent calcium channels. This action may help prevent or treat excessive intestinal motility ...
The muscle damage that will weaken you at 60 may begin decades earlier. Not as soreness or fatigue, but as a microscopic cascade you cannot feel: damaged proteins piling up, calcium pumps seizing, the ...
