Oligodendrocyte-derived LGI3 and its receptor ADAM23 organize juxtaparanodal Kv1 channel clustering for short-term synaptic plasticity.
Title: Oligodendrocyte-derived LGI3 and its receptor ADAM23 organize juxtaparanodal Kv1 channel clustering for short-term synaptic plasticity.
Taken together, these results support the critical involvement of LGI3 in the cytokine network by interplaying with multiple adipokines, cytokines and signaling proteins.
Title: Leucine-rich glioma inactivated 3: Integrative analyses support its role in the cytokine network.
findings show LGI3 and TNF-alpha upregulated each other in 3T3-L1 cells; study suggests LGI3 is a pro-inflammatory adipokine and forms a positive feedback loop with TNF-alpha; propose that LGI3 is a member of adipokine network that plays regulatory roles in obesity-associated adipose tissue inflammation
Title: Leucine-rich glioma inactivated 3 and tumor necrosis factor-α regulate mutually through NF-κB.
results suggested that LGI3 may participate in adipose tissue homeostasis by negatively regulating adiponectin
Title: Leucine-rich glioma inactivated 3 associates negatively with adiponectin.
Data suggest that leucine-rich glioma inactivated 3 (LGI3) may be a candidate adipokine that is perturbed in obesity and suppresses adipogenesis through its receptor, ADAM23.
Title: Leucine-rich glioma inactivated 3 regulates adipogenesis through ADAM23.
LGI3 interacts with Flo1 in the brain, and LGI3/Flo1 mediates APP trafficking and exosome formation in neuronal cells: reveals the details of the intracellular transport system and even the secretion pathway in the brain.
Title: LGI3 interacts with flotillin-1 to mediate APP trafficking and exosome formation.
we propose that LGI3 is a neuritogenic factor whose signaling pathway involves Akt-mediated FAK activation.
Title: Leucine-rich glioma inactivated 3 induces neurite outgrowth through Akt and focal adhesion kinase.
LGI3 gene widespread expression in the brain suggests that its transcripts might be involved in a common cellular process present in different neuronal types.

LGI3 may play a regulatory role in neuronal exocytosis via its interaction with syntaxin 1.
Title: Leucine-rich glioma inactivated 3 associates with syntaxin 1.
Data show that LGI3 localizes to the endocytic pathway and its accumulation is caused by endocytic perturbation.
Title: Leucine-rich glioma inactivated 3 is involved in amyloid beta peptide uptake by astrocytes and endocytosis itself.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
