Annotation description:- DIP2A is involved in acetylated coenzyme A (Ac-CoA) synthesis and is primarily expressed in the brain regions with abundant pyramidal neurons.

- DIP2A is localized to dendritic spines in excitatory neurons (Fig.1) - shown with Western Blot of synaptosomes and fluorescence microscopy of cultured neurons

- deletion of Dip2a in mice induces defects in spine morphogenesis along with thin
postsynaptic density (PSD), and reduced synaptic transmission of pyramidal neurons (Fig. 2) - as shown with fluorescence microscopy, whole-cell patch clamp, Western Blot and TEM

- DIP2A interacts with cortactin, an activity-dependent spine remodelling protein, and modulates its acetylation (Fig. 3) - shown by Western Blot of mural brain lysates and fluorescence microscopy

- Acetylation cortactin is critical for DIP2A-regulated synaptic transmission. Acetylation mimetic cortactin rescues synaptic defects. (Fig. 6) - shown with whole-cell patch clamp of 8KQ infected Dip2a KO neurons at DIV10
