Structures of APC/C(Cdh1) with substrates identify Cdh1 and Apc10 as the D-box co-receptor.
(NATURE PUBLISHING GROUP, 2011-02-10)
The ubiquitylation of cell-cycle regulatory proteins by the large multimeric anaphase-promoting complex (APC/C) controls sister chromatid segregation and the exit from mitosis. Selection of APC/C targets is achieved through ...
Ubiquitylation of MLKL at lysine 219 positively regulates necroptosis-induced tissue injury and pathogen clearance.
(NATURE PORTFOLIO, 2021-06-07)
Necroptosis is a lytic, inflammatory form of cell death that not only contributes to pathogen clearance but can also lead to disease pathogenesis. Necroptosis is triggered by RIPK3-mediated phosphorylation of MLKL, which ...
Autoinhibition Mechanism of the Ubiquitin-Conjugating Enzyme UBE2S by Autoubiquitination.
(CELL PRESS, 2019-08-06)
Ubiquitin-conjugating enzymes (E2s) govern key aspects of ubiquitin signaling. Emerging evidence suggests that the activities of E2s are modulated by posttranslational modifications; the structural underpinnings, however, ...
LUBAC determines chemotherapy resistance in squamous cell lung cancer.
(ROCKEFELLER UNIV PRESS, 2019-02-04)
Lung squamous cell carcinoma (LSCC) and adenocarcinoma (LADC) are the most common lung cancer subtypes. Molecular targeted treatments have improved LADC patient survival but are largely ineffective in LSCC. The tumor ...
Ubiquitin-Mediated Regulation of RIPK1 Kinase Activity Independent of IKK and MK2.
(CELL PRESS, 2018-02-15)
Tumor necrosis factor (TNF) can drive inflammation, cell survival, and death. While ubiquitylation-, phosphorylation-, and nuclear factor κB (NF-κB)-dependent checkpoints suppress the cytotoxic potential of TNF, it remains ...
Mind Bomb Regulates Cell Death during TNF Signaling by Suppressing RIPK1's Cytotoxic Potential.
(CELL PRESS, 2018-04-10)
Tumor necrosis factor (TNF) is an inflammatory cytokine that can signal cell survival or cell death. The mechanisms that switch between these distinct outcomes remain poorly defined. Here, we show that the E3 ubiquitin ...
RavN is a member of a previously unrecognized group of Legionella pneumophila E3 ubiquitin ligases.
(PUBLIC LIBRARY SCIENCE, 2018-02-01)
The eukaryotic ubiquitylation machinery catalyzes the covalent attachment of the small protein modifier ubiquitin to cellular target proteins in order to alter their fate. Microbial pathogens exploit this post-translational ...
Phosphorylation-mediated interactions with TOPBP1 couple 53BP1 and 9-1-1 to control the G1 DNA damage checkpoint.
(ELIFE SCIENCES PUBLICATIONS LTD, 2019-05-28)
Coordination of the cellular response to DNA damage is organised by multi-domain 'scaffold' proteins, including 53BP1 and TOPBP1, which recognise post-translational modifications such as phosphorylation, methylation and ...
Proteasomal degradation of the tumour suppressor FBW7 requires branched ubiquitylation by TRIP12.
(NATURE RESEARCH, 2021-04-06)
The tumour suppressor FBW7 is a substrate adaptor for the E3 ubiquitin ligase complex SKP1-CUL1-F-box (SCF), that targets several oncoproteins for proteasomal degradation. FBW7 is widely mutated and FBW7 protein levels are ...
Vaccinia E5 is a major inhibitor of the DNA sensor cGAS.
(NATURE PORTFOLIO, 2023-05-22)
The DNA sensor cyclic GMP-AMP synthase (cGAS) is critical in host antiviral immunity. Vaccinia virus (VACV) is a large cytoplasmic DNA virus that belongs to the poxvirus family. How vaccinia virus antagonizes the cGAS-mediated ...
