Tryptophan Metabolite Indole‐3‐Aldehyde Induces AhR and c‐MYC Degradation to Promote Tumor Immunogenicity

open access: yesAdvanced Science, EarlyView.
Tryptophan metabolite Indole‐3‐aldehyde (I3A) downregulates cytosolic AhR and p‐ERK/c‐MYC proteins, together enhancing STAT3 phosphorylation and tumor immunogenicity. Overexpression of the Trp metabolic enzyme interleukin‐4‐induced gene‐1 (IL4I1) in tumor cells increases intracellular levels of I3A and enhances tumor immunogenicity.

Acod1 Promotes PAD4 Ubiquitination via UBR5 Alkylation to Modulate NETosis and Exert Protective Effects in Sepsis

open access: yesAdvanced Science, EarlyView.
In this study, Acod1 knockout in CLP mice significantly increases peripheral blood NET levels, exacerbating inflammation, organ damage, and reducing survival. Further research shows that UBR5 interacts with PAD4, a key NET formation protein. Acod1/itaconate (ITA) enhances the enzymatic activity of UBR5 by alkylating the Cys2768 site, promoting the K48 ...

Proteasome Lid Bridges Mitochondrial Stress with Cdc53/Cullin1 NEDDylation Status [PDF]

open access: yes, 2019
Cycles of Cdc53/Cullin1 rubylation (a.k.a NEDDylation) protect ubiquitin-E3 SCF (Skp1-Cullin1-F-box protein) complexes from self-destruction and play an important role in mediating the ubiquitination of key protein substrates involved in cell cycle ...

USP10 Inhibits Ferroptosis via Deubiquinating POLR2A in Head and Neck Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
This study identifies USP10 as a novel deubiquitinase that antagonizes ferroptosis in head and neck squamous cell carcinoma (HNSCC). Mechanistically, USP10 directly stabilizes POLR2A protein through post‐translational deubiquitination, enabling POLR2A‐mediated transcriptional activation of SLC7A11, a key ferroptosis inhibitor.

The proteasome biogenesis regulator Rpn4 cooperates with the unfolded protein response to promote ER stress resistance

open access: yes, 2019
Misfolded proteins in the endoplasmic reticulum (ER) activate the unfolded protein response (U PR), which enhances protein folding to restore homeostasis.

IKK phosphorylates Huntingtin and targets it for degradation by the proteasome and lysosome [PDF]

open access: yes, 2009
Expansion of the polyglutamine repeat within the protein Huntingtin (Htt) causes Huntington's disease, a neurodegenerative disease associated with aging and the accumulation of mutant Htt in diseased neurons.

DNA‐PKcs‐Driven YAP1 Phosphorylation and Nuclear Translocation: a Key Regulator of Ferroptosis in Hyperglycemia‐Induced Cardiac Dysfunction in Type 1 Diabetes

open access: yesAdvanced Science, EarlyView.
In the context of chronic hyperglycemia, a DDR is initiated, leading to the pathological activation of DNA‐PKcs in the diabetic heart. This activated DNA‐PKcs directly interacts with and phosphorylates YAP1 at Thr226, thereby increasing the nuclear expression of YAP1.

MYC Binding Near Transcriptional End Sites Regulates Basal Gene Expression, Read‐Through Transcription, and Intragenic Contacts

open access: yesAdvanced Science, EarlyView.
MYC is a transcription factor (TF) that binds DNA near transcriptional start sites (TSSs) and within enhancer elements. Here, unappreciated sites of MYC binding in the vicinity of transcriptional end sites (TESs) of many genes in multiple cell types in association with numerous other TFs are described previously.

20S and 26S proteasome-binding proteins of the rabbit brain: A proteomic dataset

open access: yesData in Brief, 2021
Fractions of 26S and 20S proteasomes isolated from the rabbit brain by the method of salt fractionation (salt-induced precipitation) contain intrinsic proteasome proteins responsible for assembly of the core particle and regulatory particle of proteasome

Identification of a functional docking site in the Rpn1 LRR domain for the UBA-UBL domain protein Ddi1

open access: yesBMC Biology, 2011
Background The proteasome is a multi-subunit protein machine that is the final destination for cellular proteins that have been marked for degradation via an ubiquitin (Ub) chain appendage.
