Abstract

Mice deficient in 14-3-3ε exhibit abnormal neuronal migration and die perinatally. We report here the first large-scale analysis of 14-3-3 interacting partners from primary animal tissue, identifying from embryonic murine brain 163 14-3-3ε interacting proteins and 85 phosphorylation sites on these proteins. Phosphorylation of the deubiquitinating enzyme USP8 at serine 680 was found essential for its interaction with 14-3-3ε and for maintaining USP8 in the cytosol.
