Nanoscale Mapping of the Subcellular Glycosylation Landscape

Advanced Science, EarlyView.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

High-resolution NMR studies of structure and dynamics of human ERp27 indicate extensive interdomain flexibility [PDF]

, 2013
ERp27 (endoplasmic reticulum protein 27.7 kDa) is a homologue of PDI (protein disulfide-isomerase) localized to the endoplasmic reticulum. ERp27 is predicted to consist of two thioredoxinfold domains homologous with the non-catalytic b and b domains of ...

Protein disulfide isomerase secretion following vascular injury initiates a regulatory pathway for thrombus formation

Nature Communications, 2017
Protein disulfide isomerase (PDI), secreted by platelets and endothelial cells on vascular injury, is required for thrombus formation. Using PDI variants that form mixed disulfide complexes with their substrates, we identify by kinetic trapping multiple ...

Intercellular Horizontal Transfer of TXNDC5 mRNA via Extracellular Vesicles Contributes to Tumor‐Associated Macrophage‐Mediated Prostate Cancer Metastasis

Advanced Science, EarlyView.
This study investigates the role of M2 macrophage‐derived extracellular vesicles (M2 EVs) in prostate cancer (PCa) metastasis. Mechanistically, M2 EVs horizontally transfer TXNDC5 mRNA to PCa cells, where the molecule induces the mesenchymal‐like state (MLS), enhancing PCa migration and invasion.

Engineered Pathways for Correct Disulfide Bond Oxidation [PDF]

, 2011
Correct formation of disulfide bonds is critical for protein folding. We find that cells lacking protein disulfide isomerases (PDIs) can use alternative mechanisms for correct disulfide bond formation.

Characterization of an A-Site Selective Protein Disulfide Isomerase A1 Inhibitor.

Biochemistry, 2018
Protein disulfide isomerase A1 (PDIA1) is an endoplasmic reticulum (ER)-localized thiol-disulfide oxidoreductase that is an important folding catalyst for secretory pathway proteins.

Modulating Purothionin Accumulation and Signal Peptide Cleavage Fine‐Tunes Wheat Flour Gluten Properties to Improve Cookie‐Making Quality

Advanced Science, EarlyView.
Dual genetic strategies for improving wheat processing quality by regulating purothionin accumulation to modulate gluten quantity and quality. The first strategy involves targeting signal peptide (SP) cleavage sites (e.g., through mutation) to indirectly reduce gluten content, thereby disrupting gluten network formation.

PDIA3 Inhibition Facilitates Sensitivity of IKE‐Induced Ferroptosis via STAT3/LCN2 Axis to Improve Glioblastoma Therapy

Advanced Science, EarlyView.
In this manuscript, protein disulfide isomerase A3 (PDIA3) is identified as a key factor mediating the susceptibility of ferroptosis in GBM. Inhibition of PDIA3 enhances IKE or cystine starvation‐induced ferroptosis in GBM cells by resulting in the accumulation of lipid peroxidation and a reduction in GSH level.
