Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Heat Shock-Induced Dephosphorylation of Eukaryotic Elongation Factor 1BδL by Protein Phosphatase 1
Several variant proteins are produced from EEF1D, including two representative proteins produced via alternative splicing machinery. One protein is the canonical translation eukaryotic elongation factor eEF1Bδ1, and the other is the heat shock-responsive

The MgATP-Dependent Protein Phosphatase and Protein Phosphatase 1 Have Identical Substrate Specificities [PDF]
The MgATP-dependent phosphorylase phosphatase was found to have a broad substrate specificity. Its activity against all phosphoproteins tested was dependent upon preincubation with the activating factor FA and MgATP. The enzyme dephosphorylated and inactivated phosphorylase kinase and inhibitor 1, and dephosphorylated and activated glycogen synthase ...

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 ...

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.

The role of histone modifications in transcription regulation upon DNA damage
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Activation of ADF/cofilin by phosphorylation-regulated Slingshot phosphatase is required for the meiotic spindle assembly in Xenopus laevis oocytes [PDF]
We identify Xenopus ADF/cofilin (XAC) and its activator, Slingshot phosphatase (XSSH), as key regulators of actin dynamics essential for spindle microtubule assembly during Xenopus oocyte maturation.

Heparin inhibits the activity of protein phosphatase‐1 [PDF]
Heparin inhibited the dephosphorylation of rabbit skeletal muscle or liver phosphorylase a by protein phosphatase‐1. Other glycosaminoglycans (chondroitin sulfates) and their constituents were found to be without effect. The chromatography of a partially purified phosphatase preparation on heparin—Sepharose CL‐6B resulted in a fraction that did not ...

Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Impact of PNKP mutations associated with microcephaly, seizures and developmental delay on enzyme activity and DNA strand break repair [PDF]
Microcephaly with early-onset, intractable seizures and developmental delay (MCSZ) is a hereditary disease caused by mutations in polynucleotide kinase/phosphatase (PNKP), a DNA strand break repair protein with DNA 5'-kinase and DNA 3'-phosphatase ...
