TRAF3: Guardian of T lymphocyte functions

Frontiers in Immunology, 2023
Tumor necrosis factor receptor (TNFR)-associated factor 3 (TRAF3) is an adapter protein with many context-specific functions. Early studies of lymphocyte TRAF3 hinted at TRAF3’s importance for T cell function, but elucidation of specific mechanisms was ...

Substrate recognition determinants of human eIF2α phosphatases

Open Biology, 2021
Phosphorylation of the translation initiation factor eIF2α is a rapid and vital cellular defence against many forms of stress. In mammals, the levels of eIF2α phosphorylation are set through the antagonistic action of four protein kinases and two ...

Symbiotic Fungi Alter the Acquisition of Phosphorus in Camellia oleifera through Regulating Root Architecture, Plant Phosphate Transporter Gene Expressions and Soil Phosphatase Activities

Journal of Fungi, 2022
Plant roots can be colonized by many symbiotic fungi, whereas it is unclear whether and how symbiotic fungi including arbuscular mycorrhizal fungi and endophytic fungi promote phosphorus (P) uptake in Camellia oleifera plants.

Ssu72 Regulates Fungal Development, Aflatoxin Biosynthesis and Pathogenicity in Aspergillus flavus

Toxins, 2020
The RNA polymerase II (Pol II) transcription process is coordinated by the reversible phosphorylation of its largest subunit-carboxy terminal domain (CTD). Ssu72 is identified as a CTD phosphatase with specificity for phosphorylation of Ser5 and Ser7 and

Change in the Activity of Acidic and Alkaline Phosphatases in Immunocompetent Organs -a Criterion for Evaluating the Effectiveness of Immunobiological Preparations

Эпидемиология и вакцинопрофилактика, 2017
Dynamics of acidic and alkaline phosphatase activities was examined in thymus and spleen of laboratory mice immunized by cell wall preparations of Francisella tularensis of different subspecies. Cell wall preparations of two subspecies: F.

WIP1 Promotes Homologous Recombination and Modulates Sensitivity to PARP Inhibitors

Cells, 2019
Genotoxic stress triggers a combined action of DNA repair and cell cycle checkpoint pathways. Protein phosphatase 2C delta (referred to as WIP1) is involved in timely inactivation of DNA damage response by suppressing function of p53 and other targets at

Dephosphorylation in nuclear reassembly after mitosis

Frontiers in Cell and Developmental Biology, 2022
In most animal cell types, the interphase nucleus is largely disassembled during mitotic entry. The nuclear envelope breaks down and chromosomes are compacted into separated masses.

Reversible phosphorylation of the 26S proteasome

Protein & Cell, 2017
The 26S proteasome at the center of the ubiquitin-proteasome system (UPS) is essential for virtually all cellular processes of eukaryotes. A common misconception about the proteasome is that, once made, it remains as a static and uniform complex with ...
