Glycine receptor, alpha 1

Glycine receptor subunit alpha-1 is a protein that in humans is encoded by the "GLRA1" gene.
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.
Clinical significance.
Mutations in the gene have been associated with hyperekplexia, a neurologic syndrome associated with an exaggerated startle reaction.
