The glycine receptor, or GlyR, is the receptor for the amino acid neurotransmitter glycine. GlyR is an ionotropic receptor that produces its effects through chloride current. It is one of the most widely distributed inhibitory receptors in the central nervous system and has important roles in a variety of physiological processes, especially in mediating inhibitory neurotransmission in the spinal cord and brain stem.
The receptor can be activated by a range of simple amino acids including glycine, β-alanine and taurine, and can be selectively blocked by the high-affinity competitive antagonist strychnine. Caffeine has recently been found to also be a competitive antagonist.

Famous quotes containing the word receptor:
“The disinterest [of my two great-aunts] in anything that had to do with high society was such that their sense of hearing ... put to rest its receptor organs and allowed them to suffer the true beginnings of atrophy.”
—Marcel Proust (1871–1922)
