Prediction of Prion Proteins in E. coli Based on Bimodal Sequence Characteristics

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Prions are infectious proteins that bear misfolded conformations capable of converting folded states into misfolded aggregates under physiologically relevant conditions. In mammals, prions cause deadly maladies including Creutzfeldt‐Jakob and chronic wasting disease. To date, several prion proteins have been identified in eukaryotes, primarily

The activation mechanism of Irga6, an interferon-inducible GTPase contributing to mouse resistance against Toxoplasma gondii [PDF]

, 2011
Background: The interferon-inducible immunity-related GTPases (IRG proteins/p47 GTPases) are a distinctive family of GTPases that function as powerful cell-autonomous resistance factors.

Effects of decreased Rac activity and malignant state on oral squamous cell carcinoma in vitro.

PLoS ONE, 2021
Rac proteins, members of the Rho family of small GTP-binding proteins, have been implicated in transducing a number of signals for various biological mechanisms, including cell cytoskeleton organization, transcription, proliferation, migration, and ...

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Fic-mediated adenylylation : catalysis and regulation [PDF]

, 2014
Adenylylation, also referred to as adenylation or AMPylation, is the process by which adenosine-5‘-monophosphate (AMP) is covalently attached to a protein, a nucleic acid, or a small molecule.

Function and regulation of Rnd proteins in cortical projection neuron migration

Frontiers in Neuroscience, 2015
The mammalian cerebral cortex contains a high variety of neuronal subtypes that acquire precise spatial locations and form long or short-range connections to establish functional neuronal circuits.

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Small GTP Binding Proteins and the Control of Phagocytic Uptake

, 2005
Phagocytosis is a conserved cellular process in Eukaryotes. A multi-step process, it involves the recognition of paniculate material, e.g., microbes and apoptotic cells, their F-actin-driven engulfment and the subsequent destruction of the phagocytized ...

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Conserved Inhibitory Mechanism and Competent ATP Binding Mode for Adenylyltransferases with Fic Fold [PDF]

, 2013
The ubiquitous FIC domain is evolutionarily conserved from bacteria to human and has been shown to catalyze AMP transfer onto protein side-chain hydroxyl groups.
