Protein Structure

UniProt Annotation

Function

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).

Subcellular Localization

Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein.

Disease Associations

Hyperekplexia 2 (HKPX2) [MIM:614619]: A neurologic disorder characterized by muscular rigidity of central nervous system origin, particularly in the neonatal period, and by an exaggerated startle response to unexpected acoustic or tactile stimuli. {ECO:0000269PubMed:11929858, ECO:0000269PubMed:21391991}. Note=The disease is caused by mutations affecting the gene represented in this entry.
