Phosphorelay signal transduction
WebIn a phosphorelay, signal ligands activate sensor histidine kinases as in a basic two-component system, but the phosphoryl group is transferred to an aspartate residue of a single-domain response regulator that lacks a DNA-binding output domain (Fig. 1). WebOne fundamental issue in signal transduction and cell decision making then is how differences in signal duration are detected to achieve the appropriate biological response. …
