DLGAP3 (DLG Associated Protein 3, also known as SAPAP3) is a postsynaptic density protein that plays a crucial role in excitatory synaptic transmission and plasticity. It is enriched in the striatum and cortex, where it interacts with PSD-95 and Shank proteins to form the core scaffold of the postsynaptic density. DLGAP3 is particularly important for synaptic targeting of metabotropic glutamate receptors and regulation of spine morphology. Mouse studies show that loss of Dlgap3 leads to obsessive-compulsive-like behaviors, suggesting its role in habit formation and compulsive behaviors.

The DLGAP3 gene has been implicated in several neurodevelopmental and neurodegenerative disorders:
DLGAP3 is highly expressed in the brain, particularly in:
Expression is localized primarily to postsynaptic densities of excitatory synapses.
The study of Dlgap3 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
