The Ligand-Gated Ion Channel database provides access to information about transmembrane proteins that exist under different conformations, with three primary subfamilies: the cys-loop superfamily, the ATP gated channels superfamily, and the glutamate activated cationic channels superfamily.**The development of the Ligand-Gated Ion Channel database was started in 1994, as part of Le Novère's work on the phylogeny of those receptors' subunits. It grew into a serious data resource, that served the community at large. However, it is not actively maintained anymore. In addition, bioinformatics technology evolved a lot over the last two decades, so that scientists can now generate quickly customised databases from trustworthy primary data resources. Therefore, we decided to officialy freeze the data resource. The resource will not disappear, and all the information and links will stay there. But people should not consider it as an up-to-date trustable resource.**
The LGIC database has been initially developed by Nicolas Le Novère within the team of Jean-Pierre Changeux at the Pasteur Institute, with the help of Catherine Letondal. It was further developed at the EMBL-EBI by Marie-Ange Djite and Antonia Mayer.
