Glycine receptor, alpha 1

Protein-coding gene in the species Homo sapiens

Glycine receptor subunit alpha-1 is a protein that in humans is encoded by the GLRA1 gene.^[5][6]

Function

The inhibitory glycine receptor mediates postsynaptic inhibition in the spinal cord and other regions of the central nervous system. It is a pentameric receptor composed solely of alpha subunits. The GLRB gene encodes the alpha subunit of the receptor.^[7]

Clinical significance

Mutations in the gene have been associated with hyperekplexia, a neurologic syndrome associated with an exaggerated startle reaction.^[8][9]
