PRMT3‐Mediated H4R3me2a Promotes Primary Age‐Related Tauopathy by Driving Tau Hyperphosphorylation in Neuron

Advanced Science, EarlyView.
This study identifies PRMT3‐mediated H4R3me2a as a critical driver of tau hyperphosphorylation in primary age‐related tauopathy. Mechanistic insights reveal that the PRMT3/H4R3me2a/miR‐448 axis suppresses IGF1R expression via epigenetic regulation, further dysregulating the PI3K/AKT/GSK3β pathway.

A non-equilibrium dynamic mechanism for the allosteric effect

, 2007
Allosteric regulation is often viewed as thermodynamic in nature. However protein internal motions during an enzymatic reaction cycle can be slow hopping processes over numerous potential barriers.

Thermodynamic and Kinetic Analysis of Sensitivity Amplification in Biological Signal Transduction [PDF]

, 2002
Based on a thermodynamic analysis of the kinetic model for the protein phosphorylation-dephosphorylation cycle, we study the ATP (or GTP) energy utilization of this ubiquitous biological signal transduction process.

Heme/NADH Mimics Co‐Decorated Allosteric Capsules for Regulating Oxygen Activation and Upregulating Intracellular Methionine Depletion

Advanced Science, EarlyView.
Through modifying the switchable µ‐oxo bridged FeIII‐porphyrins moiety and NADH mimics into a metal‐organic capsule, multiple responsive manners for O2 activation, chemical oxygenation and metabolic transformation have been demonstrated for upregulating intracellular methionine depletion and accumulation of methionine sulfoxide to achieve effective ...

Probing the activity modification space of the cysteine peptidase cathepsin K with novel allosteric modifiers.

PLoS ONE, 2014
Targeting allosteric sites is gaining increasing recognition as a strategy for modulating the activity of enzymes, especially in drug design. Here we investigate the mechanisms of allosteric regulation of cathepsin K as a representative of cysteine ...

Parsimonious evolutionary scenario for the origin of allostery and coevolution patterns in proteins

, 2019
Proteins display generic properties that are challenging to explain by direct selection, notably allostery, the capacity to be regulated through long-range effects, and evolvability, the capacity to adapt to new selective pressures.

Longitudinal Analysis of Neuroradiological Biomarkers for Fragile X‐Associated Tremor/Ataxia Syndrome and Implications for Clinical Trials

Annals of Neurology, EarlyView.
Objective The objective of this study was to show the capacity of structural brain magnetic resonance imaging (MRI) measures to serve as monitoring biomarkers for Fragile X‐Associated Tremor/Ataxia Syndrome (FXTAS). Methods From 2 longitudinal studies of male FMR1 premutation carriers, 2 brain MRI scans were selected from each participant, collected ...
