General annotation (Comments)

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).
Subunit structure	Pentamer composed of alpha and beta subunits. Interacts with GPHN By similarity.
Subcellular location	Cell junction › synapse › postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein.
Involvement in disease	Defects in GLRB are a cause of startle disease (STHE) [MIM:149400]; also known as hereditary hyperekplexia or congenital stiff-person syndrome. STHE is a genetically heterogeneous 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. Inheritance can be autosomal dominant or recessive. Ref.6
Sequence similarities	Belongs to the ligand-gated ion channel (TC 1.A.9) family. Glycine receptor (TC 1.A.9.3) subfamily. GLRB sub-subfamily. [View classification]
