Chromatin structure is altered following DNA replication stress through the activity of protein kinase C signalling which leads to functionally coupled histone H3 phosphorylation and acetylation events.
ATM plays an important role in maintaining the fidelity of DNA repair through the regulation of ARP8 phosphorylation to prevent the chromosome abnormality.
Fibroblast growth factor induces dephosphorylation and inactivation of the NPR2 guanylyl cyclase, thus decreasing cyclic GMP production in growth plate chondrocytes and contributing to FGF-dependent decreases in bone growth.
ULK3 is a kinase in the abscission checkpoint that temporarily inactivates ESCRT-III proteins via phosphorylation, which is required to delay cytokinesis in response to defects in mitosis.
Phosphoproteomics identifies β-arrestin 2 phosphorylation at Thr383 by MEK as a key step of GPCR-induced Erk½ activation, thus providing new insight into the molecular mechanism underlying β-arrestin-dependent GPCR-operated signaling.
Phosphorylation of a highly conserved serine residue is a physiological response of Escerichia coli to environmental potassium levels that inhibits transport by KdpFABC to maintain cellular homeostasis.
The cancer testis antigen COX6B2 enhances cytochrome c oxidase activity thereby promoting proliferation and survival in cancer cells and represents a therapeutic target for inhibiting oxidative phosphorylation selectively in tumors.
In addition to increasing glycolysis, some proliferating cells exhibiting the Warburg effect also increase oxidative phosphorylation through mitochondrial fusion.
Phosphorylation of Aurora A does not trigger a population shift to the active state as previously thought, but instead switches the kinase on by tuning the structure and dynamics of a dynamically sampled subpopulation.
