Abstract:Wild-type p53-induced phosphatase (Wip1) is induced by p53 in response to various stresses, resulting in the dephosphorylation of proteins (i.e., p38 MAPK, p53, and uracil DNA glycosylase) involved in DNA repair and cell cycle checkpoint pathways. The p38 MAPK-p53 pathway has been a unique way for Wip1 induction as a stress responder. Here, we show that c-Jun directly binds to and activates the Wip1 promoter in response to UV irradiation. Mutation of the p53 response element (p53RE) or c-Jun consensus sites re… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
