DLGAP3 Gene
Introduction
Dlgap3 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

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](/brain-regions/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.

Function
DLGAP3 (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.
Disease Associations
The DLGAP3 gene has been implicated in several neurodevelopmental and neurodegenerative disorders:
Autism Spectrum Disorder: Rare variants in DLGAP3 have been identified in patients with ASD.
Intellectual Disability: Loss-of-function mutations contribute to intellectual disability phenotypes.
Obsessive-Compulsive Disorder: DLGAP3 (particularly SAPAP3/DLGAP3) has been linked to OCD-like behaviors in mouse models.
Expression
DLGAP3 is highly expressed in the brain, particularly in:
Cerebral cortex
[Hippocampus](/brain-regions/hippocampus)
[Striatum](/brain-regions/striatum)
[Cerebellum](/brain-regions/cerebellum)
Expression is localized primarily to postsynaptic densities of excitatory synapses.
Key Publications
