The Ligand Gated Ion Channel Database
The ligand gated ion channels (LGICs) are ionotropic receptors to neurotransmitters. Their physiological effect is carried out by the opening of an ionic channel upon binding of a particular neurotransmitter. These LGICs constitute superfamilies of receptors formed by homologous subunits. A database has been developed to handle the growing wealth of cloned subunits. This database contains nucle...
متن کاملLGICdb: the ligand-gated ion channel database
Ligand-Gated Ion Channels (LGIC) are polymeric transmembrane proteins involved in the fast response to numerous neurotransmitters. All these receptors are formed by homologous subunits and the last two decades revealed an unexpected wealth of genes coding for these subunits. The Ligand-Gated Ion Channel database (LGICdb) has been developed to handle this increasing amount of data. The database ...
متن کاملThe Ligand Gated Ion Channel database: an example of a sequence database in neuroscience.
Multiple comparisons of receptor sequences, or receptor subunit sequences, has proved to be an invaluable tool in modern pharmacological investigations. Although of outstanding importance, general sequence databases suffer from several imperfections due to their size and their non-specificity. Room therefore exists for expert-maintained databases of restricted focus, where knowledge of the rese...
متن کاملMonod-Wyman-Changeux Analysis of Ligand-Gated Ion Channel Mutants.
We present a framework for computing the gating properties of ligand-gated ion channel mutants using the Monod-Wyman-Changeux (MWC) model of allostery. We derive simple analytic formulas for key functional properties such as the leakiness, dynamic range, half-maximal effective concentration ([EC50]), and effective Hill coefficient, and explore the full spectrum of phenotypes that are accessible...
متن کاملAmphetamine activates/potentiates a ligand-gated ion channel
pAper type 294 Channels Volume 8 Issue 4 AutoCommentAry Amphetamine (Amph) is a psycho-stimulant illegally used as a performance enhancer and widely prescribed to treat attention deficit hyperactive disorder (ADHD). Despite its therapeutic use for nearly a century to treat different mental disorders, the mechanism of Amph action is still not fully understood. Similarly to other drugs of abuse, ...
