Each cell of the human body contains two meters of DNA. The whole secret lies in the intricate three-dimensional arrangement that allows DNA strands to be efficiently organized and compacted within ...

Rho (Ras-homologous) GTPases apparently play an important role. These proteins process signals within cells and regulate, among other things, growth, differentiation into the genetically ...

Furthermore, signaling from Rho and ROCK promotes mitochondrial fission through regulating Drp1’s recruitment to mitochondria. These findings suggest that RhoA and ROCK may couple or coordinate the ...

Technically, all food sources give the body energy in calories, but protein is not the body's primary energy source. Protein does contribute to our overall, long-term energy levels by promoting ...

Rho GTPases cycle between an active form bound to GTP (blue arrows) and an inactive form that is attached to GDP (red arrows). Binding to guanosine nucleotide is induced by GEF proteins. GAP proteins ...

In particular, the molecular cell biologist wanted to know what proteins are produced at any given moment. So his laboratory came up with a way to directly measure the output of ribosomes — the ...

These affordable foods deliver plenty of protein to perform all the essential functions the macronutrient is responsible for — and keep you satisfied. Sufficient protein each day is a worthy ...
