Microglial Deubiquitinase OTUD7B Stabilizes STAT3 to Promote Neuroinflammation and Cognitive Decline in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
. ABSTRACT Neuroinflammation driven by microglial activation is a defining feature of Alzheimer's disease (AD), yet the molecular mechanisms sustaining this proinflammatory state remain unclear. Here, we identify the deubiquitinase OTUD7B as a critical regulator of microglial activation and AD pathology.

The FA Core Complex Contains a Homo-dimeric Catalytic Module for the Symmetric Mono-ubiquitination of FANCI-FANCD2

open access: yesCell Reports, 2017
Activation of the main DNA interstrand crosslink repair pathway in higher eukaryotes requires mono-ubiquitination of FANCI and FANCD2 by FANCL, the E3 ligase subunit of the Fanconi anemia core complex. FANCI and FANCD2 form a stable complex; however, the

The Role of Ubiquitination in Regulation of Innate Immune Signaling

open access: yes, 2015
Ubiquitination, also denoted ubiquitylation, is a posttranslational modification that has been implicated in the regulation of both innate and adaptive immune responses. Ubiquitination plays crucial roles in innate immune signaling by ensuring the proper

A Clinical Study of Decellularized Tissue Engineering Hyaline Cartilage Graft (dLhCG) for Articular Cartilage Repair

open access: yesAdvanced Science, EarlyView.
ABSTRACT Current clinical approaches for knee cartilage repair are often limited by hypertrophy and fibrosis in the regenerated tissues. A decellularized tissue‐engineered hyaline cartilage graft (dLhCG), composed of a type II collagen‐based extracellular matrix, has been developed to overcome this limitation.

The Expanding Universe of Ubiquitin and Ubiquitin-Like Modifiers [PDF]

open access: yesPlant Physiology, 2012
The post-translation addition of ubiquitin (Ub) and structurally related polypeptide modifiers to other intracellular constituents is now known to be an important intermediate driving a wide assortment of metabolic and regulatory processes in plants. Although the most common targets are other proteins, conjugation of specific modifiers to lipids and ...

Loss of E3 Ubiquitin Ligase RINES via CpG Methylation Relieves Suppression of STAT3 and MYC, Facilitating Multiple Tumorigeneses

open access: yesAdvanced Science, EarlyView.
Dysregulated protein modifications drive tumorigenesis. RINES, an E3 ubiquitin ligase, represses tumor cell proliferation and metastasis by facilitating RING domain‐dependent, ubiquitin–proteasome‐mediated degradation of STAT3 and MYC, which consequently restrains cancer stemness and oncogenic progression.

Presynaptic protein ubiquitination and synaptic transmission [PDF]

open access: yes, 2018
Ubiquitination of a target protein is an important post-translational modification. There is evidence for the involvement of ubiquitination of presynaptic proteins in synaptic transmission.

GTPase Rac1 et ubiquitination

open access: yes, 2007
Cette thèse a été consacrée à l étude de la régulation par ubiquitination d une protéine de signalisation cellulaire, la GTPase Rac1. J ai montré que l ubiquitination dégradative de Rac1 affecte peu son variant d épissage Rac1b, et qu elle requiert l ...

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice

open access: yesAdvanced Science, EarlyView.
This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...

Molecular Mechanisms of TRAF6 Ubiquitination and Activation [PDF]

open access: yes, 2009
The Tumor Necrosis Factor (TNF) Receptor Associated Factor 6 (TRAF6) is an intracellular signal transducers, being responsible for mediating many of the activation events initiated by TNF receptor (TNFR) and Toll-like/Interleukin-1 and 18 receptor (TIR ...
