A Family of Novel Cyclophilins, Conserved in the Mimivirus Genus of the Giant DNA Viruses

Computational and Structural Biotechnology Journal, 2018
The cyclophilin (abbreviated here as CYN) family represents a large group of protein prolyl isomerase (PPIase), many of which are also chaperones that promote proper folding of a large variety of client proteins. Over the past few years, megaviruses with

Peptidyl-Prolyl Cis/Trans Isomerase Pin1 and Alzheimer’s Disease

Frontiers in Cell and Developmental Biology, 2020
Alzheimer’s disease (AD) is the most common cause of dementia with cognitive decline. The neuropathology of AD is characterized by intracellular aggregation of neurofibrillary tangles consisting of hyperphosphorylated tau and extracellular deposition of ...

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Prolyl isomerases in gene transcription

Biochimica et Biophysica Acta (BBA) - General Subjects, 2015
Peptidyl-prolyl isomerases (PPIases) are enzymes that assist in the folding of newly-synthesized proteins and regulate the stability, localization, and activity of mature proteins. They do so by catalyzing reversible (cis-trans) rotation about the peptide bond that precedes proline, inducing conformational changes in target proteins.This review will ...

s-cyclophilin is retained intracellularly via a unique COOH-terminal sequence and colocalizes with the calcium storage protein calreticulin [PDF]

, 1992
Cyclophilins (cyclosporin A-binding proteins) are conserved, ubiquitous, and abundant proteins that accelerate the isomerization of XaaPro peptide bonds and the refolding of proteins in vitro.

The Mycobacterium tuberculosis Rv0132c Gene Product Mtb‐FGD2 Can Act as an F420‐Dependent Glucose Dehydrogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The role of the cell envelope‐associated Rv0132c/FGD2 from Mycobacterium tuberculosis has long been a subject of debate. Importantly, FGD2 is found only in pathogenic mycobacteria, making it a potential drug target. While some suggest it functions as a glucose‐6‐phosphate dehydrogenase, others propose it acts instead as an F420‐dependent ...

Generalizing the Gaussian Network Model: Spanning‐Tree Thermodynamics Shows Entropy‐Driven KRAS Activation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The GTPase KRAS executes a conformational switch between a GTP‐bound active state and a GDP‐bound inactive state, a process central to oncogenic signaling. However, the structural basis of this switching at the level of residue‐contact organization remains incompletely characterized by traditional binary structural models.

Targeting protein–protein interactions with reversible covalent modalities: Non‐cysteine chemistries

British Journal of Pharmacology, EarlyView.
Abstract Protein–protein interactions (PPIs) are central to diverse cellular functions, and represent a rapidly expanding class of therapeutic targets. Advancements in covalent drug design have enabled small‐molecule drugs to overcome challenges associated with engaging these targets, such as limited durations of action and difficult‐to‐drug (expansive,

Involvement of prolyl isomerase PIN1 in the cell cycle progression and proliferation of hepatic oval cells

, 2017
Liver regenerates remarkably after toxic injury or surgical resection. In the case of failure of resident hepatocytes to restore loss, repopulation is carried out by induction, proliferation, and differentiation of the progenitor cell.

Functional characterization of 42 CK2α de novo variants associated with Okur‐Chung neurodevelopmental syndrome

The FEBS Journal, EarlyView.
Okur‐Chung neurodevelopmental syndrome (OCNDS) is a neurodevelopmental disorder associated with mutations in the gene coding for Protein kinase CK2α. In this work, 42 variants of CK2α associated with OCNDS were characterized in vitro. This included determination of catalytic activity and CK2α/CK2β‐interaction as well as an assessment of evolutionary ...
