摘要
Recently mutations in the LGI1 (leucine-rich, gliomainactivated 1) gene have been found in human temporal lobe epilepsy. We have now identified three formerly unknown LGI-like genes. Hydropathy plots and pattern analysis showed that LGI genes encode proteins with large extra- and intracellular domains connected by a single transmembrane region. Sequence analysis demonstrated that LGI1, LGI2, LGI3, and LGI4 form a distinct subfamily when compared to other leucine-rich repeat-containing proteins. In silico mapping and radiation hybrid experiments assigned LGI2, LGI3, and LGI4 to different chromosomal regions (4p15.2, 8p21.3, 19q13.11), some of which have been implicated in epileptogenesis and/or tumorigenesis.
