Individual cells translate concentration gradients of extracellular factors into all-or-none threshold responses leading to discrete patterns of gene expression. Signaling cascades account for some bu...
The defining activity of the homeodomain protein Nanog is the ability to confer cytokine-independent self-renewal upon ES (embryonic stem) cells in which it is overexpressed. However, the biochemical ...
MAP kinase cascades are inherently switch-like, but, during yeast mating, MAPK signaling is graded. A new study suggests that the Ste5 scaffold protein is responsible for making this switch less switc...
The CXXC active-site motif of thiol-disulfide oxidoreductases is thought to act as a redox rheostat, the sequence of which determines its reduction potential and functional properties. We tested this ...
