DLGAP4 (DLG Associated Protein 4) is a member of the SAPAP family of postsynaptic density proteins. It participates in synaptic scaffolding and signal transduction at excitatory synapses. DLGAP4 interacts with PSD-95 and contributes to the organization of postsynaptic density complexes. It is expressed in various brain regions including the [hippocampus](/brain-regions/hippocampus) and [cortex](/brain-regions/cortex). Beyond synaptic function, DLGAP4 has been implicated in cell polarity and division, with altered expression observed in certain cancers.

DLGAP4 (DLG Associated Protein 4) is a member of the SAPAP family of postsynaptic density proteins. It participates in synaptic scaffolding and signal transduction at excitatory synapses. DLGAP4 interacts with PSD-95 and contributes to the organization of postsynaptic density complexes. It is expressed in various brain regions including the [hippocampus](/brain-regions/hippocampus) and [cortex](/brain-regions/cortex). Beyond synaptic function, DLGAP4 has been implicated in cell polarity and division, with altered expression observed in certain cancers.
Function
DLGAP4 is a member of the SAPAP family of postsynaptic density proteins. It participates in synaptic scaffolding and signal transduction at excitatory synapses. DLGAP4 interacts with PSD-95 and contributes to the organization of postsynaptic density complexes. It is expressed in various brain regions including the hippocampus and cortex. Beyond synaptic function, DLGAP4 has been implicated in cell polarity and division, with altered expression observed in certain cancers.
Disease Associations
The DLGAP4 gene has been implicated in several neurodevelopmental and neurodegenerative disorders:
Autism Spectrum Disorder: Rare variants in DLGAP4 have been identified in patients with ASD.
Intellectual Disability: Loss-of-function mutations contribute to intellectual disability phenotypes.
Cancer: Altered expression of DLGAP4 has been observed in certain cancers.
Expression
DLGAP4 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
Research linking DLGAP4 to synaptic function and disease associations continues to expand our understanding.
The study of Dlgap4 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.
