Genes upregulated by p53 were screened using an erythroleukemic cell line (1-2-3) that expresses only the temperature-sensitive p53 by the mRNA differential display method. One of the upregulated genes was identified as the elongation factor-1 alpha (EF-1 alpha) gene, an essential component of the eukaryotic translation apparatus, Three p53-responsive elements were found in the mouse EF-1 alpha gene and in the corresponding human, rat, and frog genes. These elements conferred the capacity for induction by p53. EF-1 alpha is also a microtubule-severing protein. Upon the temperature-shift, the cells developed the morphology and the localization of alpha-tubulin similar to those of the cells treated with vincristine, a drug that affects microtubules. The microtubule-severing associated with upregulation of EF-1 alpha by p53 may be a cause of the cell death.
