Dynamic protein interactions probed by NMR spectroscopy

Bulletin of the Korean Chemical Society, Volume 46, Issue 7, Page 680-690, July 2025.
Abstract Dynamic protein–protein interactions are essential for diverse cellular processes but often evade structural characterization due to their transient, heterogeneous, and disordered nature. This review focuses on how nuclear magnetic resonance (NMR) spectroscopy can provide detailed, residue‐level insights into these complex interactions.

To translate, or not to translate: viral and host mRNA regulation by interferon-stimulated genes. [PDF]

, 2015
Type I interferon (IFN) is one of the first lines of cellular defense against viral pathogens. As a result of IFN signaling, a wide array of IFN-stimulated gene (ISG) products is upregulated to target different stages of the viral life cycle.

PKR associates with 4.1R to promote anchorage-independent growth of hepatocellular carcinoma and lead to poor prognosis

Scientific Reports
RNA-dependent protein kinase (PKR) may have a positive regulatory role in controlling tumor growth and progression in hepatocellular carcinoma (HCC). However, the downstream substrates and the molecular mechanism of PKR in the growth and progression of ...

Change in Nutritional Status Modulates the Abundance of Critical Pre-initiation Intermediate Complexes During Translation Initiation \u3cem\u3ein Vivo\u3c/em\u3e [PDF]

, 2007
In eukaryotic translation initiation, eIF2∙GTP–Met-tRNAiMet ternary complex (TC) interacts with eIF3–eIF1–eIF5 complex to form the multifactor complex (MFC), while eIF2∙GDP associates with eIF2B for guanine nucleotide exchange.

Molecular Determinants of the Regulation of Development and Metabolism by Neuronal eIF2α Phosphorylation in [PDF]

, 2017
Cell-nonautonomous effects of signaling in the nervous system of animals can influence diverse aspects of organismal physiology. We previously showed that phosphorylation of Ser49 of the α-subunit of eukaryotic translation initiation factor 2 (eIF2α) in ...

Endoplasmic Reticulum Stress Amplifies Cytokine Responses in Astrocytes via a PERK/eIF2α/JAK1 Signaling Axis

Glia, EarlyView.
ER stress amplifies TNF‐α, OSM, and IL‐1β responses in astrocytes. PERK and JAK1 signaling are required for the synergistic interaction between ER stress and inflammatory cytokines. Translational suppression attenuates the synthesis of the negative feedback regulators IκBα and SOCS3.

Two RNA-binding motifs in the double-stranded RNA-activated protein kinase, DAI [PDF]

, 1992
The protein kinase DAI, the double-stranded RNA-activated inhibitor of translation, is an essential component of the interferon-induced cellular antiviral response. The enzyme is regulated by the binding of activator and inhibitor RNAs.

Covalent Inhibition of the Peptidyl‐Prolyl Isomerase Pin1 by Sulfopin Results in a Broad Impact on the Phosphoproteome of Human Osteosarcoma U2‐OS Cells

PROTEOMICS, Volume 25, Issue 14, July 2025.
ABSTRACT Peptidyl‐prolyl isomerase, NIMA‐interacting protein 1‐(Pin1) catalyses the cis–trans interconversion of the inflexible bond between serine or threonine residues and proline at the +1 position (pSer/pThr‐Pro). Although initially discovered as an essential regulator of cell division, Pin1 has since been identified as a regulator of many ...

Short‐Term Severe Energy Restriction Promotes Molecular Health and Reverses Aging Signatures in Adults With Prediabetes in the PREVIEW Study

Aging Cell, EarlyView.
Severe short‐term energy restriction in adults with prediabetes led to a significant reduction in circulating proteins linked to inflammation, senescence, and protein turnover. These changes, partly mediated by extracellular vesicles, suggest systemic dietary‐induced benefits beyond glycemic control, including improved aging biomarkers.
