Distinct Conformational Switches Control WPD‐Loop Dynamics Across Protein Tyrosine Phosphatase Subfamilies

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Protein Tyrosine Phosphatases (PTPs) regulate cellular signaling by balancing phosphotyrosine levels through a conserved WPD‐loop that switches between open (inactive) and closed (active) conformations. While this conformational change is crucial for catalysis, the structural factors governing this motion remain poorly understood.

The Histidine 382 Residue Influences the Thermal Stability and Binding Propensity of the E2 Domain of Amyloid Precursor Protein

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The E2 domain of amyloid precursor protein (APP_E2) plays a central role in the protein's function. We reinvestigate how the missense mutation, ΔH382L, affects the domain's thermal stability and ligand binding propensity through differential scanning fluorometry.

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Evolution of the SARS‐CoV‐2 Main Protease Under Fitness Constraints Imposed by Folding Stability and Activity

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) continues to evolve and diversify, leading to the emergence of immune‐evasive variants and underscoring the need for complementary antiviral strategies targeting conserved viral machinery. In this context, the main protease (Mpro) represents a potential therapeutic target because

Schisandrin C Targets PPARγ to Induce Ferroptosis in Colorectal Cancer Cells and Promote M1 Macrophage Polarization

open access: yesPhytotherapy Research, EarlyView.
Schisandrin C: A Dual Anti‐Colorectal Cancer Strategy Targeting PPARγ. ABSTRACT Colorectal cancer (CRC) remains a leading cause of cancer mortality, necessitating novel therapeutic strategies. Schisandrin C (SinC), a bioactive lignan from Schisandra chinensis, exhibits diverse pharmacological activities, but its anti‐CRC mechanisms are poorly ...
