Personalized phosphoproteomics establish mTORC1 as a regulator of exercise-induced insulin sensitization in human skeletal muscle

Magnus R. Leandersson, Hannah Huckstep, Johan Onslev…·Jørgen F. P. Wojtaszewski

The paper uses personalized phosphoproteomics to show that mTORC1 regulates exercise-induced insulin sensitization in human skeletal muscle through a feedback pathway involving MKNK2 and eIF4G1.

Loss of T73T75 phosphorylation on PP2A-B56Par1 advances mitotic entry and reduces S. pombe cell size

Lenka Hálová, Yvonne Connolly, Duncan L. Smith…·Iain Hagan

The paper identifies that phosphorylation of T73T75 on PP2A-B56Par1 by CDK1-Cyclin B delays mitotic entry and increases cell size in S. pombe.

Unconventional binding of Calmodulin to CHK2 kinase inhibits catalytic activity

Christopher R. Horne, Tingting Wang, Samuel N. Young…·James M. Murphy

The paper identifies an unconventional mechanism where Ca2+-CaM binds CHK2 kinase to inhibit its activity, contrasting with its typical role in promoting kinase activity.
