The ubiquitin codes in cellular stress responses

Protein & Cell, Journal Year: 2023, Volume and Issue: 15(3), P. 157 - 190

Published: July 19, 2023

Ubiquitination/ubiquitylation, one of the most fundamental post-translational modifications, regulates almost every critical cellular process in eukaryotes. Emerging evidence has shown that essential components numerous biological processes undergo ubiquitination mammalian cells upon exposure to diverse stresses, from exogenous factors reactions, causing a dazzling variety functional consequences. Various forms ubiquitin signals generated by ubiquitylation events specific milieus, known as codes, constitute an intrinsic part myriad stress responses. These events, leading proteolytic turnover substrates or just switch functionality, initiate, regulate, supervise multiple stress-associated responses, supporting adaptation, homeostasis recovery, and survival stressed cells. In this review, we attempted summarize crucial roles response different environmental intracellular while discussing how stresses modulate system. This review also updates recent advances understanding machinery well responses discusses some important questions may warrant future investigation.

Discovery of Deactivation Phenomenon in NiCo₂S₄/NiS₂ Electromagnetic Wave Absorbent and Its Reactivation Mechanism

Small Methods, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 7, 2024

Abstract Over the past century, extensive research has been carried out on various types of microwave absorption (MA) materials, primarily emphasizing mechanism, performance, and even toward smart device. However, deactivation, a crucial concern for practical applications, long long‐neglected. In this work, an in‐depth exploration deactivation mechanism reveals significant competition between metal oxygen, leading to replacement S‐M (M = Ni Co) bond by new S─O surface absorber. This substitution initiates series collapse effect that introduces additional defective sites diminishes potential charge transport. Subsequently, passive active anti‐deactivation strategies are developed target deactivation. The strategy involved intentionally creating electron‐deficient structures at initial Co in crystal through Fe doping engineering, with objective preventing generation bonds. Furthermore, allows precise control absorber reactivation employing accelerated thermodynamic kinetic methods, enabling reversible transformation competitive reactions Finally, fast method is first proposed promising stimulate further innovations breakthroughs applications.

Regulation of Phosphoribosyl-Linked Serine Ubiquitination by Deubiquitinases DupA and DupB

Molecular Cell, Journal Year: 2019, Volume and Issue: 77(1), P. 164 - 179.e6

Published: Nov. 12, 2019

The family of bacterial SidE enzymes catalyzes non-canonical phosphoribosyl-linked (PR) serine ubiquitination and promotes infectivity Legionella pneumophila. Here, we describe identification two effectors that reverse PR are thus named deubiquitinases for (DUPs; DupA DupB). Structural analyses revealed ubiquitin ligases harbor a highly homologous catalytic phosphodiesterase (PDE) domain. However, unlike ligases, displays increased affinity to PR-ubiquitinated substrates, which allows cleave from substrates. Interfering with DupA-ubiquitin binding switches its activity toward SidE-type ligase. Given the high exploited catalytically inactive mutant trap identify more than 180 host proteins in Legionella-infected cells. Proteins involved endoplasmic reticulum (ER) fragmentation membrane recruitment Legionella-containing vacuoles (LCV) emerged as major targets. global map substrates provides critical insights into host-pathogen interactions during infection.
