Usage of Cell-Free Protein Synthesis in Post-Translational Modification of μ-Conopeptide PIIIA

Marine Drugs, 2023
The post-translational modifications of conopeptides are the most complicated modifications to date and are well-known and closely related to the activity of conopeptides.

Unfolding Plant Defence: Endoplasmic Reticulum Stress Signalling at the Plant‐Pathogen Interface

Plant Biotechnology Journal, EarlyView.
ABSTRACT The endoplasmic reticulum (ER) stress response, a conserved proteostasis network, has emerged as a central hub that reprograms plant immunity during pathogen attack. This review synthesises how plants harness ER‐stress signalling to mount multilayered defences and how pathogens have evolved counterstrategies to subvert these pathways.

Function of PIN1 in Cancer Development and Its Inhibitors as Cancer Therapeutics

Frontiers in Cell and Developmental Biology, 2020
Peptidyl-prolyl isomerase (PIN1) specifically binds and isomerizes the phosphorylated serine/threonine–proline (pSer/Thr–Pro) motif, which results in the alteration of protein structure, function, and stability.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, EarlyView.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

Protein folding: Prolyl isomerases join the fold [PDF]

Current Biology, 1995
Cyclophilins have prolyl isomerase activity, but evidence for their suggested role in protein folding in cells has been scarce; now they have been found to accelerate the folding of mitochondrial precursor proteins.

Prolyl isomerase Pin1 regulates mouse embryonic fibroblast differentiation into adipose cells. [PDF]

PLoS ONE, 2012
A peptidyl prolyl cis/trans isomerase, Pin1, regulates insulin signal transduction. Pin1 reduces responses to insulin stimulation by binding CRTC2 (CREB-regulated transcriptional co-activator 2) and PPARγ (peroxisome prolifereator- activated receptor γ),

Adenine nucleotide translocator and ATP synthase cooperate in mediating the mitochondrial permeability transition

The Journal of Physiology, EarlyView.
Abstract figure legend Both ATP synthase and adenine nucleotide translocator (ANT) play key roles in mediating the permeability transition. The contribution of ANT becomes evident in the presence of atractylate (ATR) at pH 6.5, a condition that prevents ATP synthase channel activity. At pH 7.4, this effect is minimal, suggesting a critical role for ATP

The prolyl isomerase Pin1 modulates development of CD8+ cDC in mice. [PDF]

PLoS ONE, 2012
Pin1 has previously been described to regulate cells that participate in both innate and adaptive immunity. Thus far, however, no role for Pin1 has been described in modulating conventional dendritic cells, innate antigen presenting cells that potently ...

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Peptidyl Prolyl Isomerase PIN1 Directly Binds to and Stabilizes Hypoxia-Inducible Factor-1α. [PDF]

PLoS ONE, 2016
Peptidyl prolyl isomerase (PIN1) regulates the functional activity of a subset of phosphoproteins through binding to phosphorylated Ser/Thr-Pro motifs and subsequently isomerization of the phosphorylated bonds.
