    Peroxiredoxin promotes longevity and H2O2-resistance in yeast through redox-modulation of protein kinase A

    Friederike Roger et al.
    The major cytosolic yeast peroxiredoxin Tsa1 controls aging and H2O2-resistance by inhibiting protein kinase A through a conserved cysteine in the catalytic subunit activation loop and not by scavenging H2O2.

    Intrinsic disorder within an AKAP-protein kinase A complex guides local substrate phosphorylation

    F Donelson Smith et al.
    Structural analysis of an AKAP18-protein kinase A complex reveals that regions of intrinsic disorder impact the phosphorylation of preferred substrates.

    Multi-state recognition pathway of the intrinsically disordered protein kinase inhibitor by protein kinase A

    Cristina Olivieri et al.
    A combination of NMR, fluorescence, and molecular dynamics simulations reveals the recognition mechanism for the intrinsically disordered regulator of protein kinase A, highlighting the enzyme's nuclear export process.

    Isoform-specific subcellular localization and function of protein kinase A identified by mosaic imaging of mouse brain

    Ronit Ilouz et al.
    High-resolution, large-scale immunohistochemical mouse brain images showing global views of different brain regions, as well as cellular and subcellular details, identified distinct localization of PKA RIβ and RIIβ regulatory subunits that reveal functional differences.

    Protein kinase C is a calcium sensor for presynaptic short-term plasticity

    Diasynou Fioravante et al.
    Genetic and electrophysiology experiments provide the first direct evidence that protein kinase C is a calcium-sensing protein in post-tetanic potentiation, a form of synaptic plasticity that supports short-term memory.

    Reciprocal regulation of ARPP-16 by PKA and MAST3 kinases provides a cAMP-regulated switch in protein phosphatase 2A inhibition

    Veronica Musante et al.
    A complex interplay between MAST3 and PKA protein kinases and the regulatory protein ARPP-16 allows cAMP to control the activity of protein phosphatase 2A.

    A secretory kinase complex regulates extracellular protein phosphorylation

    Jixin Cui et al.
    A pseudokinase in the secretory pathway, Fam20A, activates the real Golgi casein kinase, Fam20C, via a unique mechanism that is lost in human diseases.

    A specific E3 ligase/deubiquitinase pair modulates TBP protein levels during muscle differentiation

    Li Li et al.
    Proteasome-mediated degradation of the TATA-box binding protein (TBP) during terminal differentiation is regulated by the E3 ligase Huwe1 and the deubiquitinase USP10.

    PRD-2 directly regulates casein kinase I and counteracts nonsense-mediated decay in the Neurospora circadian clock

    Christina M Kelliher et al.
    Casein kinase I, a pivotal kinase in the circadian clock encoded by ck-1a, is positively regulated by a novel RNA-binding protein that protects ck-1a transcripts from nonsense-mediated decay.
