GLRA4 (Q5JXX5) - Overview - Molecular Target Synopsis


GLRA4, Glycine receptor subunit alpha-4
UniProt Q5JXX5

Also Known as GLRA4_HUMAN, GLRA4

Glycine receptors are ligand-gated chloride channels. Channel opening is triggered by extracellular glycine. Channel opening is also triggered by taurine and beta-alanine. Plays a role in the down-regulation of neuronal excitability. Contributes to the generation of inhibitory postsynaptic currents. Homopentamer (in vitro). Pentamer composed of alpha and beta subunits.
