Comparative Genome Analyses of Plant Rust Pathogen Genomes Reveal a Confluence of Pathogenicity Factors to Quell Host Plant Defense Responses

open access: yesPlants, 2022
Switchgrass rust caused by Puccinia novopanici (P. novopanici) has the ability to significantly affect the biomass yield of switchgrass, an important biofuel crop in the United States. A comparative genome analysis of P.

Differential activity of rice protein disulfide isomerase family members for disulfide bond formation and reduction

open access: yesFEBS Open Bio, 2014
Protein disulfide isomerases (PDIs), a family of thiol-disulfide oxidoreductases that are ubiquitous in all eukaryotes, are the principal catalysts for disulfide bond formation. Here, we investigated three rice (Oryza sativa) PDI family members (PDIL1;1,

Molecular Chaperones in Cancer Stem Cells: Determinants of Stemness and Potential Targets for Antitumor Therapy

open access: yesCells, 2020
Cancer stem cells (CSCs) are a great challenge in the fight against cancer because these self-renewing tumorigenic cell fractions are thought to be responsible for metastasis dissemination and cases of tumor recurrence. In comparison with non-stem cancer

Myricetin, the Main Flavonoid in Syzygium cumini Leaf, Is a Novel Inhibitor of Platelet Thiol Isomerases PDI and ERp5

open access: yesFrontiers in Pharmacology, 2020
BackgroundFlavonoids have been characterized as a prominent class of compounds to treat thrombotic diseases through the inhibition of thiol isomerases. Syzygium cumini is a flavonoid-rich medicinal plant that contains myricetin and gallic acid. Little is

Metal‐Responsive Up‐Regulation of Bifunctional Disulfides for Suppressing Protein Misfolding and Promoting Oxidative Folding

open access: yesAngewandte Chemie, EarlyView.
A stress‐responsive folding promotor was developed by conjugating metal‐binding ligands and a redox‐active disulfide. The oxidative strength of the bifunctional disulfide was enhanced by metal coordination, inhibiting protein misfolding and up‐regulating the oxidative folding capacity under metal stress.

Increasing melanoma cell death using inhibitors of protein disulfide isomerases to abrogate survival responses to endoplasmic reticulum stress.

open access: yesCancer Research, 2008
Exploiting vulnerabilities in the intracellular signaling pathways of tumor cells is a key strategy for the development of new drugs. The activation of cellular stress responses mediated by the endoplasmic reticulum (ER) allows cancer cells to survive ...

Disulfide isomerase ERp57 improves the stability and immunogenicity of H3N2 influenza virus hemagglutinin

open access: yesVirology Journal, 2020
Background Hemagglutinin (HA), as the surface immunogenic protein, is the most important component of influenza viruses. Previous studies showed that the stability of HA was significant for HA’s immunogenicity, and many efforts have been made to ...

Importance of disulphide bonds for vaccinia virus L1R protein function

open access: yesVirology Journal, 2005
L1R, a myristylated late gene product of vaccinia virus, is essential for formation of infectious intracellular mature virions (IMV). In its absence, only viral particles arrested at an immature stage are detected and no infectious progeny virus is ...

Novel Protein-disulfide Isomerases from the Early-diverging Protist Giardia lamblia *

open access: yesJournal of Biological Chemistry, 1999
Protein-disulfide isomerase is essential for formation and reshuffling of disulfide bonds during nascent protein folding in the endoplasmic reticulum. The two thioredoxin-like active sites catalyze a variety of thiol-disulfide exchange reactions. We have

Interactome analyses identify ties of PrP and its mammalian paralogs to oligomannosidic N-glycans and endoplasmic reticulum-derived chaperones. [PDF]

open access: yesPLoS Pathogens, 2009
The physiological environment which hosts the conformational conversion of the cellular prion protein (PrP(C)) to disease-associated isoforms has remained enigmatic.
