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.
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.
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.
Phosphorylation of Spc110 N-terminal domain encompassing conserved motifs and its interaction with conserved GCP3 N-terminal domain regulate the oligomerization of gamma-tubulin small complexes (γ-TuSCs).
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.
