PROTAC‐Engineered Protein/DNA Nanoantigen is a Potent Booster for Dendritic Cell Vaccines in Cancer Immunotherapy

Advanced Science, EarlyView.
A PROTAC‐functionalized protein/DNA‐integrated nanoantigen platform is developed to enhance dendritic cell vaccine potency. By combining a VHL‐recruiting peptide‐modified antigen with a sustained expression plasmid within CaCO3 nanoparticles, this system amplifies cross‐presentation, promotes DC maturation, and elicits robust Th1 and CTL responses ...

E3 ubiquitin ligase that recognizes sugar chains

Nature, 2002
N-glycosylation of proteins in the endoplasmic reticulum (ER) has a central role in protein quality control. Here we report that N-glycan serves as a signal for degradation by the Skp1-Cullin1-Fbx2-Roc1 (SCF(Fbx2)) ubiquitin ligase complex. The F-box protein Fbx2 (ref. 4) binds specifically to proteins attached to N-linked high-mannose oligosaccharides

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells

Advanced Science, EarlyView.
BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

USP30‐Mediated Deubiquitination of PEX5 Suppresses Pexophagy to Drive Tubular Injury in Diabetic Kidney Disease

Advanced Science, EarlyView.
USP30 accumulation in diabetic renal tubular epithelial cells deubiquitinates PEX5, suppresses pexophagy, and drives dysfunctional peroxisome accumulation and tubular injury. USP30 depletion restores PEX5 ubiquitination and pexophagy, improves peroxisomal function, and alleviates tubular damage, highlighting USP30 as a therapeutic target in diabetic ...

The Role of the Cullin-5 E3 Ubiquitin Ligase in the Regulation of Insulin Receptor Substrate-1

Biochemistry Research International, 2012
Background. SOCS proteins are known to negatively regulate insulin signaling by inhibiting insulin receptor substrate-1 (IRS1). IRS1 has been reported to be a substrate for ubiquitin-dependent proteasomal degradation.

Loss of LCN2 Function Ameliorates Glucocorticoid‐Induced Muscle Atrophy via Remodeling the Extracellular Matrix

Advanced Science, EarlyView.
Glucocorticoids transcriptionally activate LCN2 expression via GR nuclear translocation. Secreted LCN2 binds MMP9 to degrade skeletal muscle ECM collagen, blocks integrin‐mediated mechanotransduction, bidirectionally disrupts muscle protein homeostasis, and reveals a novel target for steroid‐induced muscle atrophy.

Ubiquitin E3 ligase MARCH10 targets influenza hemagglutinin for ubiquitination

Cellular Signalling
Influenza virus infection damages the airways and can cause acute lung injury. Influenza virus infection remains difficult to combat since treatment is limited to supportive care or antiviral drugs to prevent influenza early in the condition. Influenza hemagglutinin (HA) is the surface glycoprotein that facilitates viral entry by binding to sialic acid-

The BTB/POZ‐MATH Protein ZmBPM1 Interacts With Autophagy‐related Protein ZmATG6 and Modulates the NLR Protein Rp1‐D21‐Mediated Defense Response in Maize

Advanced Science, EarlyView.
The maize BTB/POZ‐MATH (BPM) protein ZmBPM1 interacts with autophagy‐related protein ZmATG6 to relocate the NLR protein Rp1‐D21 from the nucleo‐cytoplasmic compartment into autophagosome‐like puncta, leading to autophagy‐mediated turnover and suppressing the hypersensitive response.
