Coactivator-associated arginine methyltransferase 1 (CARM1) is an important target in hematologic malignancies. In this work, the authors show that the hyperactivation of Janus kinase 2 (JAK2) by the V617F mutation phosphorylates CARM1 which regulates its methyltransferase activity and alters its target specificity.

Unveiling the regulation of mitotic protein degradation is crucial for cancer therapy. Here, the authors reveal that a reciprocal inhibition of PIN1-APC/C^CDH1 controls the cell cycle and mitotic protein degradation, offering a synergistic anti-tumor strategy.

Here the authors characterise the impact of phosphorylation site mutations in intrinsically disordered regions (IDRs) on protein-protein interactions, highlighting the critical role of phosphorylation of IDRs in health and disease.

The repair of DNA double strand breaks is strictly controlled during the cell cycle by the CDK kinase. Here the authors identify the DDK kinase as a second major regulator for this cell cycle regulation and elucidate its functional targets.

How the production of piRNA is regulated remains elusive. Here the authors showed that casein kinase II mediated direct phosphorylation of USTC component TOFU-4 promotes piRNA production.

Ventricular arrhythmias are associated with aging and are a leading cause of sudden cardiac death. A new study shows that hyperactivation of p38γ/δ MAPKs is a key driver of stress-induced ventricular arrhythmias via increased phosphorylation of ryanodine receptor 2 at Ser2367 and impaired localization of potassium voltage-gated channel K_v4.3.

In tumours, cancer cells can overcome energy stress via differential regulation of non-canonical ‘moonlighting’ functions of metabolic enzymes. A study now shows that the metabolic phosphatase fructose-1,6-bisphosphatase 1 (FBP1) can act as a nuclear protein phosphatase and reveals how this process is inhibited in cancer cells.
