14-3-3 proteins, particularly the 14-3-3θ isoform, are neuroprotective in several models of Parkinson's disease (PD). Evidence for increased 14-3-3θ phosphorylation observed in PD and other neurodegenerative diseases points to a possible pathogenic role for 14-3-3θ phosphorylation in neurodegenerative disease. We recently created a novel conditional knock-in mouse to express the 14-3-3θ S232D phosphomimetic mutation. After crossing this conditional knock-in mouse with the Emx1-Cre mouse in order to induce expression of the S232D mutation in the cortex and hippocampus, we evaluated the effect of 14-3-3θ phosphorylation on behavior and pathology. These mice demonstrated mild motor deficits and reduced social dominance behavior but showed normal cognition and anxiety levels compared to Cre control mice. S232D mice did not show any α-synuclein or phospho-tau pathology at baseline, and dendritic arborization was normal in primary hippocampal cultures from S232D mice. Overall, this mouse model is a novel tool that can be used to look at the effect of 14-3-3θ phosphorylation at S232 in the context of neurodegenerative disease models.
