No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of ...

That eventually causes the muscle to move. The ACTN3 gene — also known as the “ speed gene ”— plays an important role in the actin and myosin contraction of muscle fibers.

The researchers discovered that α directly relates to what happens between two proteins within muscle cells: namely, myosin motors, the proteins that drive muscle contraction, detach faster at higher ...

We also collaborate with computational cell biologists to model how NMIIA forces exerted on the nanoscale network structure determine microscale membrane curvature and biconcave shapes. Read more ...

Depending on how you need to use your muscles, the myosin fibers either tighten up and shorten or loosen up and stretch out. Myosin is also responsible for muscle contractions like your heartbeat ...

As expected, PP1c was translocated to the cell membrane upon blue light illumination being exposed upon the OptoMYPT expressing cells, and consequently, actin and myosin-mediated contractile force ...

The emergence of asymmetry from an initially symmetrical state is a universal transition in nature. Living organisms show asymmetries at the molecular, cellular, tissular, and organismal level.
