Glycine is one of the major inhibitory neurotransmitters in the spinal cord and brain stem.
Glycine acts on the strychnine-sensitive glycine receptors, a pentameric Cl-channel, to generate inhibitory postsynaptic potentials.
Glycine can modulate excitatory neurotransmission as an obligatory co-agonist with glutamate at NMDA-activated glutamate receptors via binding site on the NMDA receptor, which is distinct from the strychnine-sensitive glycine receptor-binding site.
Glycinergic synapses are primarily present throughout the spinal cord, brain stem and cerebellum, as well as in the retina and a few other brain regions.
Neurotransmitter action is terminated by re-uptake of glycine via specific high affinity transporter protein located at the plasma membrane of neuron and glial cells.
The glycine transporter belongs to a family of Na/Cl-dependent neurotransmitter transporters, predicted to contain as many as 12 transmembrane domains.
Glycine receptor exists in 2 forms (GLYT1 and GLYT2).
Form 1 has three other known isoform (GLYT1a, GLYT1b and GLYT1c) which may be produced by alternative spicing or promoter usage.
Rodent GLYT1a and GLYT1b differ only by 10 amino acid at the N-terminus and expressed from the same gene.
Applications:Suitable for use in ELISA.
Western Blot, though not tested, may potentially be used as an application.
