Physical State | Liquid |
Immunogen | KLH conjugated synthetic peptide derived from human LGI1/ETL1 |
Epitope Specificity | 451-557/557 |
Isotype | IgG |
Purity | affinity purified by Protein A |
Buffer | 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. |
SUBCELLULAR LOCATION | Secreted. Cell junction, synapse (By similarity). Note=Isoform 1 but not isoform 2 is secreted. Isoform 1 is enriched in the Golgi apparatus while isoform 2 accumulates in the endoplasmic reticulum. |
SIMILARITY | Contains 7 EAR repeats.Contains 3 LRR (leucine-rich) repeats.Contains 1 LRRCT domain.Contains 1 LRRNT domain |
SUBUNIT | Oligomer (By similarity). Interacts with KCNA1 within a complex containing KCNA1, KCNA4 and KCNAB1 (By similarity). Part of a complex containing ADAM22, DLG4/PSD95 and CACNG2 (stargazin) (By similarity). Can bind to ADAM11 and ADAM23 (By similarity). |
Post-translational modifications | Glycosylated. |
DISEASE | Defects in LGI1 are the cause of lateral temporal lobe epilepsy autosomal dominant (ADLTE) [MIM:600512]; also known as autosomal dominant partial epilepsy with auditory features (ADPEAF). ADLTE is a form of epilepsy characterized by partial seizures, usually preceded by auditory signs. |
Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. |
Background Descriptions | 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. Tissue specificity;Predominantly expressed in neural tissues, especially in brain. Expression is reduced in low-grade brain tumors and significantly reduced or absent in malignant gliomas. Isoform 1 is absent in the cerebellum and is detectable in the occipital cortex and hippocampus; higher amounts are observed in the parietal and frontal cortices, putamen, and, particularly, in the temporal neocortex, where it is 3.5 times more abundant than in the hippocampus (at protein level). Isoform 3 shows the highest expression in the occipital cortex and the lowest in the hippocampus (at protein level). |
