Abstract


Yap8p, a member of the Saccharomyces cerevisiae Yap family, is activated in response to arsenic. Both the mechanisms by which this activation takes place and its regulation have not yet been identified. In this report, we show that Yap8p is not activated at the transcriptional level but, rather, its nuclear transport is actively regulated and dependent on the exportin chromosome region maintenance protein. In addition, it is shown that Cys(132), Cys(137)and Cys(274) are essential for Yap8p localization and transactivation function both of which are required for its biological activity.
