A protein called CDC7, long thought to play an essential role early in the cell division process, is in fact replaceable by another protein called CDK1, according to a study by investigators at Weill Cornell Medicine and the Dana Farber Cancer Institute. The finding represents a fundamental advance in cell biology and may lead to new cancer therapies, since cancers frequently alter the molecular machinery of cell division to sustain their rapid growth.
