Supplementary information

SAP97 also known as Synapse-associated protein 97 or DLG1 is a member of the membrane-associated guanylate kinase (MAGUK) family. It has a molecular mass of approximately 97 kDa. This protein is well-expressed in several tissues with high levels observed within the brain and cardiac muscles. SAP97 plays an essential role in organizing synaptic proteins and maintaining cell polarity by aiding in the trafficking and localization of certain ion channels and receptors across the plasma membrane.
Biological function summary

The function of SAP97 is closely linked to synaptic plasticity and signal transduction. This protein forms part of larger protein complexes that include ion channels and receptors helping regulate the transmission of signals between neurons. In the brain SAP97 facilitates the clustering of neurotransmitter receptors at synapses including AMPA receptors which are vital for excitatory synaptic transmission. Its role extends to modulating the structural organization and functional regulation of these protein complexes at synaptic junctions.

Pathways

SAP97 is involved in key signaling processes particularly the glutamatergic synapse pathway where it influences the trafficking and surface expression of glutamate receptors. It interacts with other MAGUK family members like PSD-95 to regulate the assembly of the postsynaptic density. This protein also plays a role in the cardiac signaling cascade particularly in interactions involving potassium channels impacting the cardiac action potential.

SAP97 has associations with neurological and cardiac conditions. Abnormal expression or mutation in SAP97 can contribute to disorders such as schizophrenia and arrhythmias. In schizophrenia disruption in SAP97 function affects synaptic communication with related proteins like PSD-95 implicated in the disease's pathology. In cardiac arrhythmias the misregulation of SAP97 interaction with ion channels might result in altered cardiac electrical activity impacting the role of proteins such as Kv4.2 in the heart's electrophysiological stability.

Target data

Essential multidomain scaffolding protein required for normal development (By similarity). Recruits channels, receptors and signaling molecules to discrete plasma membrane domains in polarized cells. Promotes epithelial cell layer barrier function via maintaining cell-cell adhesion (By similarity). May also play a role in adherens junction assembly, signal transduction, cell proliferation, synaptogenesis and lymphocyte activation. Regulates the excitability of cardiac myocytes by modulating the functional expression of Kv4 channels. Functional regulator of Kv1.5 channel. During long-term depression in hippocampal neurons, it recruits ADAM10 to the plasma membrane (PubMed : 23676497).
