Gene Information

Description

General description

L-Glutamic acid is an amino acid mainly used as a flavor enhancer in the food industry. It occurs naturally in kelp. L-Glutamic acid is said to impart umami-like taste in ready-to-drink (RTD) green tea.

Biochem/physiol Actions

An excitatory amino acid neurotransmitter that is an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA).

Mechanistic studies on the formation of pyrazines by Maillard reaction between L-ascorbic acid and L-glutamic acid.

Molecular mechanisms and therapeutical implications of intramembrane receptor/receptor interactions among heptahelical receptors with examples from the striatopallidal GABA neurons.

Luigi F Agnati et al.

Pharmacological reviews, 55(3), 509-550 (2003-07-19)

The molecular basis for the known intramembrane receptor/receptor interactions among G protein-coupled receptors was postulated to be heteromerization based on receptor subtype-specific interactions between different types of receptor homomers. The discovery of GABAB heterodimers started this field rapidly followed by

Locomotor rhythm generation linked to the output of spinal shox2 excitatory interneurons.

Kimberly J Dougherty et al.

Neuron, 80(4), 920-933 (2013-11-26)

Locomotion is controlled by spinal networks that generate rhythm and coordinate left-right and flexor-extensor patterning. Defined populations of spinal interneurons have been linked to patterning circuits; however, neurons comprising the rhythm-generating kernel have remained elusive. Here, we identify an ipsilaterally
