Abstract: A translational switch The protein known as 14-3-3σ is an important p53-regulated human tumour suppressor that is lost early in cancer development. A possible molecular basis for its function has now been found. While mRNA translation normally switches from a 'cap-dependent' to 'cap-independent' mechanism during mitosis, cells lacking 14-3-3σ don't make this switch, and consequently have cell division abnormalities.
