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 ...

Some of these mechanisms have recently been discovered and various proteins of different classes have been seen to be involved. In this section we will review such proteins and explain their ...

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 ...
