A dividing cell tags more than 14,000 different sites on its proteins with phosphate, a molecule that typically serves as a signal for a variety of biological processes. This preponderance of signals--more than twice the number identified by past studies--suggests that the cell may become a control freak during the division process, regulating each of its parts, no matter how obscure.
