Lig_chan-Glu_bd

Ligated ion channel L-glutamate- and glycine-binding site
Lig_chan-Glu_bd
SMART accession number:SM00918
Description: This region, sometimes called the S1 domain, is the luminal domain just upstream of the first, M1, transmembrane region of transmembrane ion-channel proteins, and it binds L-glutamate and glycine. It is found in association with Lig_chan.
Interpro abstract (IPR019594):

This region, sometimes called the S1 domain, is the luminal domain just upstream of the first, M1, transmembrane region of transmembrane ion-channel proteins, and binds L-glutamate and glycine in the ionotropic glutamate receptor NMDA [ (PUBMED:10465381) (PUBMED:8428958) ]. It is found in association with IPR001320 .

Ionotropic Receptors (IRs) are a variant subfamily of the Ionotropic glutamate receptors (iGluRs). In IRs, the ligand binding domain lacks one or more residues that directly contact the glutamate ligand in iGluRs [ (PUBMED:20808886) ].

GO component:membrane (GO:0016020)
GO function:ionotropic glutamate receptor activity (GO:0004970)
