Functional characterisation of a predicted chloroplastic plant protein phosphatase [PDF]
The phosphatase AtPTPKISI is involved in the control of starch metabolism in Arabidopsis thaliana leaves at night. The SEX4 (Starch Excess 4) mutants, lacking this predicted phosphatase, have strongly reduced rates of starch metabolism.

Metazoan mitosis requires remodelling of sub-cellular structures to ensure proper division of cellular and genetic material. Faults often lead to genomic instability, cell cycle arrests and disease onset.

Identification of AKAP79 as a Protein Phosphatase 1 Catalytic Binding Protein [PDF]
The ubiquitously expressed and highly promiscuous protein phosphatase 1 (PP1) regulates many cellular processes. Targeting PP1 to specific locations within the cell allows for the regulation of PP1 by conferring substrate specificity. In the present study, we identified AKAP79 as a novel PP1 regulatory subunit.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Functional cdc25C dual-specificity phosphatase is required for S-phase entry in human cells
In view of the common regulatory mechanism that induces transcription of tie mitotic phosphatase cdc25C and cyclin A at the beginning of S-phase, we investigated whether cdc25C was required for S-phase transit.

Microcystins: Potent xenobiotics [PDF]
Having in mind that exposure to low levels of microcystin in drinking water represents the health risk for people, microcystins can be observed as potent xenobiotics.

Targeting Protein Phosphatase 1 in Heart Failure [PDF]
See related article, pages 756–766 Over the past three decades the treatment of heart failure has shifted from a palliative care approach to a more successful focus on neurohormonal modulation through drugs that inhibit β-adrenergic, angiotensin, and aldosterone signaling.

Folding of Intrinsically Disordered Protein Phosphatase 1 Regulatory Proteins [PDF]
Intrinsically disordered but biologically active proteins, commonly referred to as IDPs, are readily identified in many biological systems and play critical roles in multiple protein regulatory processes. While disordered in their unbound states, IDPs often, but not always, fold upon binding with their protein interaction partners. Here, we discuss how

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Protein phosphatase 1 regulates the stability of the circadian protein PER2 [PDF]
The circadian clock is regulated by a transcription/translation negative feedback loop. A key negative regulator of circadian rhythm in mammals is the PER2 (mammalian PERIOD 2) protein. Its daily degradation at the end of the night accompanies de-repression of transcription. CKIϵ (casein kinase I ϵ) has been identified as the kinase that phosphorylates
