Resumen:
Previous studies have demonstrated that double phosphorylation of a
protein can lead to bistability if some conditions are fulfilled. It was
also shown that the signaling behavior of a covalent modification cycle
can be quantitatively and, more importantly, qualitatively modified
when this cycle is coupled to a signaling pathway as opposed to being
isolated. This property was named retroactivity. These two results are
studied together in this paper showing the existence of interesting
phenomena--oscillations and bistability--in signaling cascades
possessing at least one stage with a double-phosphorylation cycle as in
MAPK cascades.
