These studies provide proof-of-concept evidence that mGlu7 activity can be modulated by positive allosteric modulation, paving the way for future therapeutics development.
TSHR homodimerization, confirmed by Foster Resonance Energy Transfer FRETT) and Bioluminescence Resonance Energy Transfer BRETT), has been shown to play a functional role in negative cooperativity by allosteric modulation [15].
The modulation of protein function by allosteric mechanisms was the first mode of regulation by PTMs to be studied.
We report that ACC2, demonstrating consistent catalytic activities with proper posttranslational biotinylation and phosphorylation, is regulated by allosteric modulation.
In addition to being a ChEI, galantamine is also believed to enhance central neurotransmission by allosteric modulation of pre- and post-synaptic nicotinic receptors.
Short-term control of glycolysis has, for many years, been thought to occur principally by allosteric modulation of PFK-1 activity [ 26].
This study provides new insight into the spatial and temporal specificity of drug action that can be provided by allosteric modulation across a GPCR homodimeric interface. May, L. T., Bridge, L. J., Stoddart, L. A., Briddon, S. J., Hill, S. J. Allosteric interactions across native adenosine-A3 receptor homodimers: quantification using single-cell ligand-binding kinetics.
It appears that all three major classes of G protein-coupled receptors (A, B and C) are amenable to allosteric modulation by small molecules.
The aspect of mechanistic process probed here is if the 'spatio-temporal' idea of obstruction of the active site by higher concentration of substrates (or an allosteric modulation by excess substrate at an alternative enzyme binding site), as advocated erstwhile, and as is depicted in Figure 1, provides an adequate explanation to the 'substrate inhibition' kinetics.
