Cascades of multisite phosphorylation control Sic1 destruction at the onset of S phase. [PDF]

open access: yes, 2011
Multisite phosphorylation of proteins has been proposed to transform a graded protein kinase signal into an ultrasensitive switch-like response. Although many multiphosphorylated targets have been identified, the dynamics and sequence of individual ...

An Affinity-directed Protein Missile (AdPROM) System for Targeted Destruction of Endogenous Proteins

open access: yesBio-Protocol, 2017
We recently reported an Affinity-directed PROtein Missile (AdPROM) system for the targeted proteolysis of endogenous proteins of interest (POI) (Fulcher et al., 2016 and 2017).

Interplay between R513 methylation and S516 phosphorylation of the cardiac voltage-gated sodium channel [PDF]

open access: yes, 2014
Arginine methylation is a novel post-translational modification within the voltage-gated ion channel superfamily, including the cardiac sodium channel, Naᵥ1.5.

On the Control of TCR Phosphorylation [PDF]

open access: yesFrontiers in Immunology, 2012
The T-cell receptor (TCR) is responsible first of all for recognizing small peptides embedded in major histocompatibility complex molecules (pMHC). The information that a complex has thus formed is then transduced across the membrane via “triggering” of the TCR.

PKCɛ switches Aurora B specificity to exit the abscission checkpoint

open access: yesNature Communications, 2016
The Aurora B abscission checkpoint is activated when DNA is retained in the cleavage furrow on completion of anaphase. Here the authors show that PKCɛ directly phosphorylates Aurora B triggering a switch in Aurora B substrate specificity to elicit ...

On the existence of Hopf bifurcations in the sequential and distributive double phosphorylation cycle [PDF]

open access: yes, 2019
Protein phosphorylation cycles are important mechanisms of the post translational modification of a protein and as such an integral part of intracellular signaling and control. We consider the sequential phosphorylation and dephosphorylation of a protein

Tissue environment, not ontogeny, defines murine intestinal intraepithelial T lymphocytes

open access: yeseLife, 2021
Tissue-resident intestinal intraepithelial T lymphocytes (T-IEL) patrol the gut and have important roles in regulating intestinal homeostasis. T-IEL include both induced T-IEL, derived from systemic antigen-experienced lymphocytes, and natural T-IEL ...

A proanthocyanidin from cinnamomum zeylanicum stimulates phosphorylation of insulin receptor in 3t3-l1 adipocytes [PDF]

open access: yes, 2006
Non-insulin-dependent diabetes mellitus is due to in large part to insulin resistance, a state where the target cells are no longer responding to ordinary levels of circulating insulin.

Proteolysis of Non-phosphorylated and Phosphorylated Tau by Thrombin [PDF]

open access: yesJournal of Biological Chemistry, 2005
The microtubule-associated protein tau aggregates intracellularly by unknown mechanisms in Alzheimer's disease and other tauopathies. A contributing factor may be a failure to break down free cytosolic tau, thus creating a surplus for aggregation, although the proteases that degrade tau in brain remain unknown.

Structural and dynamic determinants for highly selective RET kinase inhibition reveal cryptic druggability

open access: yesJournal of Advanced Research, 2023
Introduction: The structural and dynamic determinants that confer highly selective RET kinase inhibition are poorly understood. Objectives: To explore the druggability landscape of the RET active site in order to uncover structural and dynamic ...
