WitrynaThe Erwinia ligand-gated ion channel (ELIC) is a bacterial homologue of eukaryotic Cys-loop ligand-gated ion channels. This protein has the potential to be a useful model for Cys-loop receptors but is unusual in that it has an aromatic residue (Phe) facing into the pore, leading to some predictions that this protein is incapable of ion flux. Witryna19 lut 2024 · They are implicated not only in the regulation of steroid receptors, exerting their action on gene expression via nuclear steroid hormone receptors, but also of ligand-gated ion channels, thereby influencing neuronal excitability.
