Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

The pivotal question is, what is the molecular mechanism behind actin activation of myosin that determines the force and velocity of muscle contraction? The importance of understanding the actin ...

Figure 2: Relative intensity and spacings of the higher (HA) and lower (LA) angle peaks of the M3 reflection. We conclude that this type of model, in which the M3 reflection is solely due to the ...

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 ...
