General description

Glycine is the simplest amino acid building block.

Application

Glycine has been used in whole-cell patch clamp recording to measure inward NMDA (N-methyl-D-aspartate) currents. It has also been used as a model organic system in crystallography to demonstrate a novel acoustic nebulization platform.

Biochem/physiol Actions

Glycine is a non-essential amino acid. Influx of calcium through the cell membrane is mediated by glycine-gated channel. Glycine participates in the synthesis of porphyrins, purine and serine. It also serves as a competitive agonist for glutamate in binding to the NMDA (N-methyl-D-aspartate) receptors. Glycine synthesis might be increased in rapidly proliferating cancer cells, due to increased demand for the amino acid.

The clinical associations of glycine receptor antibodies have not yet been described fully. We identified prospectively 52 antibody-positive patients and collated their clinical features, investigations and immunotherapy responses. Serum glycine receptor antibody endpoint titres ranged from 1:20 to 1:60 000.
