Binding of gephyrin to the GlyR is exclusively mediated by the E domain; the binding site was mapped to one of its sub-domains; a high affinity and low affinity binding site for the GlyRbeta-loop was found on holo-gephyrin and the E domain

Putative activation mechanisms were fitted to single-channel recordings at 4 glycine concentrations from rat alpha1beta receptors expressed in HEK293 cells. A substantial conformation change is caused by binding while the channel is still shut.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
