EFP1 is an ER stress-induced glycoprotein which interacts with the pro-apoptotic protein Par-4 [PDF]

open access: yes, 2009
We have isolated the rat ortholog of EFP1 (EF-hand binding protein 1) as a novel interaction partner of the pro-apoptotic protein Par-4 (prostate apoptosis response-4).

Improved proteomic analysis of nuclear proteins, as exemplified by the comparison of two myelo\"id cell lines nuclear proteomes [PDF]

open access: yes, 2012
One of the challenges of the proteomic analysis by 2D-gel is to visualize the low abundance proteins, particularly those localized in organelles. An additional problem with nuclear proteins lies in their strong interaction with nuclear acids.

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Protein disulfide isomerase regulation by nitric oxide maintains vascular quiescence and controls thrombus formation

open access: yesJournal of Thrombosis and Haemostasis, 2018
Essentials Nitric oxide synthesis controls protein disulfide isomerase (PDI) function. Nitric oxide (NO) modulation of PDI controls endothelial thrombogenicity. S‐nitrosylated PDI inhibits platelet function and thrombosis. Nitric oxide maintains vascular

Endoplasmic reticulum stress and the unfolded protein response in lung diseases: molecular pathways and therapeutic interventions

open access: yesThe Journal of Pathology, EarlyView.
Abstract Endoplasmic reticulum stress (ERS) occurs when the protein‐folding capacity of the endoplasmic reticulum (ER) is overwhelmed, triggering the unfolded protein response (UPR) to restore homeostasis. However, severe or persistent ERS can shift the UPR toward pro‐inflammatory, apoptotic, and fibrotic signaling, thereby exacerbating tissue injury ...

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

open access: yesNature 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 ...

Expression of Functional Human Sialyltransferases ST3Gal1 and ST6Gal1 in Escherichia coli.

open access: yesPLoS ONE, 2016
Sialyltransferases (STs) are disulfide-containing, type II transmembrane glycoproteins that catalyze the transfer of sialic acid to proteins and lipids and participate in the synthesis of the core structure oligosaccharides of human milk.

Prompting Fab Yeast Surface Display Efficiency by ER Retention and Molecular Chaperon Co-expression. [PDF]

open access: yes, 2019
For antibody discovery and engineering, yeast surface display (YSD) of antigen-binding fragments (Fabs) and coupled fluorescence activated cell sorting (FACS) provide intact paratopic conformations and quantitative analysis at the monoclonal level, and ...

Review

open access: yes, 2020
The chalcogen elements oxygen, sulfur, and selenium are essential constituents of side chain functions of natural amino acids. Conversely, no structural and biological function has been discovered so far for the heavier and more metallic tellurium ...
