Identification of E3 ligase substrates and PROTAC-induced ubiquitylation sites using proximity-based identification of ubiquitin sites (PrIUS)

Communications Biology
The ubiquitin system regulates virtually all cellular processes, yet the vast majority of ubiquitylation sites identified in the human proteome cannot be attributed to specific E3 ligases.

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

Advanced 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.

Structural Diversity of Ubiquitin E3 Ligase [PDF]

The post-translational modification of proteins regulates many biological processes. Their dysfunction relates to diseases. Ubiquitination is one of the post-translational modifications that target lysine residue and regulate many cellular processes ...

Psychological Stress Associated Bile Acid Reprogramming Promotes Hepatocellular Carcinoma Progression

Advanced 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.

Targeting GALNT7 Disrupts the TAZ O‐GalNAcylation Feedback Loop to Suppress Gallbladder Cancer Progression

Advanced Science, EarlyView.
Aberrant GALNT7‐mediated O‐GalNAcylation stabilizes TAZ to drive gallbladder cancer progression through a feed‐forward transcriptional loop. Structure‐based screening identifies Olaparib as a potent GALNT7 antagonist that disrupts this oncogenic axis, providing an immediate therapeutic strategy for this aggressive malignancy.

TRAF6 Lactylation in Glycolytic Macrophages Drives NF‐κB Signaling and M1 Polarization During Orthodontic Tooth Movement

Advanced Science, EarlyView.
Schematic diagram showing compressive stress triggers glycolytic reprogramming and lactate accumulation in macrophages. Lactate mediates TRAF6 lactylation at K171/K180 dual sites, which enhances its K63‐linked ubiquitination to activate the NF‑κB pathway and promote M1 polarization. This cascade drives orthodontic tooth movement (OTM) and alveolar bone

Targeted Degradation of STING by a Neutrophil Membrane‐Coated Nanoplatform Suppresses Microglial Pyroptosis After Subarachnoid Hemorrhage

Advanced Science, EarlyView.
MG1@NM‐Px serves as a microglia‐targeted STING‐degrading nanoplatform for subarachnoid hemorrhage. Following systemic administration, it crosses the blood–brain barrier and accumulates in activated microglia. STP1‐mediated STING ubiquitination and degradation suppress MAPK/inflammasome signaling, GSDME‐mediated pyroptosis, and IL‐1β release, revealing ...

Ubiquitination of ACSL4 by Parkin Suppresses Ferroptosis and Rescues Glucocorticoid‐Induced Bone Loss

Advanced Science, EarlyView.
GCs reduce Parkin, leading to ACSL4 accumulation and PUFA‐phospholipid‐driven ferroptosis in BMSCs, which impairs osteogenesis and promotes adipogenesis, causing GIOP. Parkin restoration (via OE‐Parkin or Parkin‐LNP@DSS6) ubiquitinates and degrades ACSL4, inhibiting ferroptosis, rescuing bone formation, and rescues GIOP bone loss.

Microprotein MP104 Promotes Malignant Progression of Colorectal Cancer Through Regulating Protein Translation

Advanced Science, EarlyView.
A previously unrecognized microprotein, MP104, encoded by ZEB1‐AS1, emerges as a critical driver of colorectal cancer progression. MP104 links ubiquitin‐mediated protein degradation with translational reprogramming via the UBE2O–AMPKα2–mTOR–EIF4B axis, revealing an unrecognized layer of oncogenic regulation.

WDR72 Promotes Neuroblastoma Stemness and Progression by Sequestering TRIM31‐Mediated Degradation of CBX8

Advanced Science, EarlyView.
This study unveiled that METTL14 mediates m6A modification of WDR72 mRNA to stabilize and enhance WDR72 expression, which disrupts TRIM31‐mediated ubiquitination of CBX8 protein and retards its degradation, finally the elevated CBX8 contributes to tumor stemness.
