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

The phosphorylation of caldesmon was studied to determine if kinase activity reflected either an endogenous kinase or caldesmon itself. Titration of kinase activity with calmodulin yielded maximum activity at substoichiometric ratios of calmodulin/caldesmon.

The E3 ubiquitin ligase ZNRF2 is a substrate of mTORC1 and regulates its activation by amino acids
The mechanistic Target of Rapamycin complex 1 (mTORC1) senses intracellular amino acid levels through an intricate machinery, which includes the Rag GTPases, Ragulator and vacuolar ATPase (V-ATPase).

HIF1a-dependent mitophagy facilitates cardiomyoblast differentiation
Mitophagy is thought to play a key role in eliminating damaged mitochondria, with diseases such as cancer and neurodegeneration exhibiting defects in this process.

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

PKCɛ switches Aurora B specificity to exit the abscission checkpoint
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 ...

Interplay between R513 methylation and S516 phosphorylation of the cardiac voltage-gated sodium channel [PDF]
Arginine methylation is a novel post-translational modification within the voltage-gated ion channel superfamily, including the cardiac sodium channel, Naᵥ1.5.

PKCε is known to exert a role in genome protection by directly phosphorylating and switching the specificity of Aurora B. Here the authors identify SERBP1 as a parallel mitotic PKCε substrate controlling translation and ensuring the integrity of ...
