Activity summary

SAP102 also known as DLG3 is a member of the membrane-associated guanylate kinase (MAGUK) protein family. This protein weighs approximately 97 kDa and is mainly expressed in the brain. SAP102 plays a significant role in signal transduction by organizing synaptic signaling complexes. It contains PDZ domains that facilitate protein-protein interactions and its expression in neuronal synapses is notable.

Biological function summary

The interaction between SAP102 and N-methyl-D-aspartate (NMDA) receptors has major implications in synapse development and plasticity. SAP102 forms part of the postsynaptic density (PSD) complex which contributes to synaptic organization and dynamics. This complex is essential for the correct functioning of synaptic signaling pathways influencing learning and memory processes.

Pathways

The regulation of synaptic plasticity and neurotransmitter release involves SAP102. In this context it plays a part in the NMDA receptor signaling pathway and the synaptic vesicle cycle. SAP102 is associated with proteins such as PSD95 and SAP97 which work together to modulate synaptic strength and communication.

Associated diseases and disorders

Abnormalities in SAP102 function or expression have links to neurodevelopmental disorders like intellectual disability and autism spectrum disorder. Mutations in SAP102 and related proteins such as neuroligins or neurexins can disrupt synaptic communication leading to defective neural circuit formation. Understanding SAP102's role in these disorders offers insights into potential therapeutic approaches.
