Glycine receptor subunit beta is a protein that in humans is encoded by the GLRB gene.[5][6][7]
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 of alpha (GLRA1, MIM 138491; GLRA2, MIM 305990) and beta subunits.[supplied by OMIM][7]
