Supplementary information

Lgi1 also known as leucine-rich glioma inactivated 1 is a synaptic protein with a mass of approximately 60 kDa. This protein is notably expressed in the brain where it plays a mechanical role in interacting with other synaptic molecules to mediate the formation and function of synaptic junctions. Lgi1 mainly associates with neuronal cell surfaces and is critical in synaptic stability and neurotransmitter release.

Biological function summary

Lgi1 influences synaptic transmission and plasticity. It forms a complex with the ADAM22 and ADAM23 proteins which are part of the disintegrin and metalloproteinase domain family. This complex regulates the activity and localization of ion channels involved in neuronal excitability influencing electrical signaling across neurons. These interactions are essential for maintaining proper neuronal communication and cognitive function.

Pathways

Several biological processes involve Lgi1 including the regulation of the voltage-gated potassium channel pathways and synaptic signaling pathways. Specifically Lgi1's interaction with ADAM22 facilitates the assembly of the postsynaptic density therefore contributing to synaptic strength. Moreover Lgi1 interacts with Kv1.1 an important partner in the modulation of ion channel activities that are central to neuronal signaling pathways.

Several conditions have a connection to Lgi1 especially autoimmune encephalitis and epilepsy. Autoimmune encephalitis often involves antibodies targeting Lgi1 affecting synaptic transmission and resulting in neurological symptoms. In epilepsy Lgi1 abnormalities potentially through disrupted interactions with related proteins like ADAM22 can lead to imbalances in neuronal excitability and trigger seizures. Understanding these connections helps in developing targeted therapies for these disorders.

Target data

Regulates voltage-gated potassium channels assembled from KCNA1, KCNA4 and KCNAB1. It slows down channel inactivation by precluding channel closure mediated by the KCNAB1 subunit. Ligand for ADAM22 that positively regulates synaptic transmission mediated by AMPA-type glutamate receptors (By similarity). Plays a role in suppressing the production of MMP1/3 through the phosphatidylinositol 3-kinase/ERK pathway. May play a role in the control of neuroblastoma cell survival.
