Reprimo, a New Candidate Mediator of the p53-mediated Cell Cycle Arrest at the G2 Phase

Abstract

A novel gene, Reprimo, in which induction in cells exposed to X-irradiation is dependent on p53 expression, has been isolated. Ectopic p53 expression results in the induction of its mRNA. Reprimo is a highly glycosylated protein and, when ectopically expressed, it is localized in the cytoplasm and induces G(2) arrest of the cell cycle. In the arrested cells, both Cdc2 activity and nuclear translocation of cyclin B1 are inhibited, suggesting the involvement of Reprimo in the Cdc2.cyclin B1 regulation pathway. Thus, Reprimo may be a new member involved in the regulation of p53-dependent G(2) arrest of the cell cycle.
