Too much of a good thing: the Prl-3 in p53's oyster.
In this issue of Molecular Cell, Basak et al. (2008) identify Prl-3 as a p53-inducible gene acting in DNA damage-induced cell-cycle arrest. Both deletion and overexpression of Prl-3 can be cytostatic, adding to a growing list of genes whose expression must be carefully titrated for proper cell proliferation.
