Protein

Glycine receptor subunit alpha-3

Gene

GLRA3

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

The glycine receptor is a neurotransmitter-gated ion channel. Binding of glycine to its receptor increases the chloride conductance and thus produces hyperpolarization (inhibition of neuronal firing).

Domaini

The N-terminal domain carries structural determinants essential for agonist and antagonist binding. TM2 is thought to form the innert wall of the chloride channel. The cytoplasmic loop is an important determinant of channel inactivation kinetics.
