DLGAP2 (DLG Associated Protein 2, also known as SAPAP2) is a postsynaptic scaffold protein highly expressed in the brain. It is a core component of the postsynaptic density (PSD) complex, where it mediates interactions between glutamate receptors, particularly AMPA receptors, and the underlying cytoskeleton. DLGAP2 plays critical roles in synaptic plasticity, learning, and memory by regulating receptor trafficking and synaptic strength. Mutations in DLGAP2 have been implicated in neurodevelopmental disorders including autism spectrum disorder and intellectual disability.

DLGAP2 plays a critical role in synaptic plasticity, learning, and memory by regulating receptor trafficking and synaptic strength. Studies have identified DLGAP2 variants in patients with autism spectrum disorder and intellectual disability, highlighting its importance in neurodevelopment and synaptic function.
The DLGAP2 gene has been implicated in several neurodevelopmental and neurodegenerative disorders:
DLGAP2 is highly expressed in the brain, particularly in:
Expression is localized primarily to postsynaptic densities of excitatory synapses.
The study of Dlgap2 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.
