title: Human prothymosin alpha inhibits division of yeast Saccharomyces cerevisiae cells, while its mutant lacking nuclear localization signal does not.
abstract: Effect of human prothymosin alpha and its mutant over-produced in S. cerevisiae on yeast cell division was studied. Wild-type prothymosin alpha appeared to block division of yeast cells. Its inhibitory action could be abolished by deletion of the last nine carboxy-terminal amino acids of prothymosin alpha containing nuclear localization signal, thus pointing to the nucleus as a compartment, where prothymosin alpha performs its action.
