Understanding K11‐ polyubiquitin recognition at the 26S Proteasome

open access: yesThe FASEB Journal, 2013
Ubiquitination, the covalent attachment of ubiquitin to target proteins, is a reversible post‐translational modification that regulates many important cellular processes. Ubiquitin chains linked at Lys48 (K48) serve as a signal for proteasomal degradation; whereas K63‐linked chains have non‐proteolytic function.

Exocellular β-Lactamases of Streptomyces albus G and Strains R39 and K11 [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1973
The β-lactamases excreted by the highly benzylpenicillin-susceptible Streptomyces strain R39 and the highly benzylpenicillin-resistant Streptomyces albus G were isolated and purified. Neither β-lactamase exhibited dd -carboxypeptidase activity. Both were anionic at

Getting Close: Insight into the Structure and Function of K11/K48-Branched Ubiquitin Chains [PDF]

open access: yesStructure, 2020
K11/K48-branched ubiquitin chains are proteasomal priority signals that elicit the rapid elimination of mitotic regulators and aggregation-prone proteins. Indicative of an intriguing signaling mode, Boughton et al. (2019) unravel an interaction between distal subunits of K11/K48-branched ubiquitin trimers that could provide a combined surface for ...

p300 Degradation by the p53‐SIAH1 Axis Relieves TBK1 Acetylation to Enhance Innate Antiviral Immunity

open access: yesAdvanced Science, EarlyView.
This study identifies p300 as the acetyltransferase that acetylates TBK1 and inhibits its phosphorylation. Activation of the p53‐SIAH1 axis by immune response downregulates p300 expression to sustain innate antiviral immunity. Conditional p300 knockout in alveolar epithelial cells in vivo promotes antiviral responses and suppresses virus replication ...

Porcine Deltacoronavirus M Protein Binds NLRP3 to Promote Inflammasome Assembly via Competition with TRIM31

open access: yesAdvanced Science, EarlyView.
Porcine deltacoronavirus (PDCoV) infection induces severe intestinal inflammation and acute diarrhea in piglets, yet the molecular mechanism remains incompletely understood. The M protein activates NLRP3 inflammasome through dual mechanisms: direct binding to the NLRP3 LRR domain and disruption of TRIM31‐mediated K48‐linked ubiquitination.

Psychological Stress Associated Bile Acid Reprogramming Promotes Hepatocellular Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
Depression is increasingly recognized as a risk factor for chronic diseases, yet its biological impact on cancer remains unclear. Using data from more than 490 000 participants across three international cohorts, we show that depression significantly increases the risk of liver cancer.

PEAR1 Promotes Glucose Metabolism Reprogramming in Sepsis‐Associated Acute Lung Injury via AARS1‐Mediated HIF‐1α Lactylation

open access: yesAdvanced Science, EarlyView.
This study revealed that a PEAR1/HIF‐1α/ glycolysis/lactate/H3K18la positive feedback loop in PMVECs that drives the development of S‐ALI. Mechanistically, PEAR1 mediates the binding of HIF‐1α to AARS1, leading to the lactylation of HIF‐1α, the primary lactylation site of which is K172.

The four known biplanes with k=11

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
The four known biplanes of order 9(k=11) are described in terms of their ovals, λ-chain structures, and automorphism groups. An exhaustive computer search for all biplanes of order 9 with certain chain structures has produced but two, one of which is new.

OTUD6A promotes prostate tumorigenesis via deubiquitinating Brg1 and AR

open access: yesCommunications Biology, 2022
OTUD6A, a deubiquitinase, is amplified in prostate cancer and correlates with poor survivability, increasing the growth of prostate cancer cell lines and PDX models.
