Tuning Butyrylcholinesterase Inactivation and Reactivation by Polymer‐Based Protein Engineering

open access: yesAdvanced Science, 2020
Organophosphate nerve agents rapidly inhibit cholinesterases thereby destroying the ability to sustain life. Strong nucleophiles, such as oximes, have been used as therapeutic reactivators of cholinesterase‐organophosphate complexes, but suffer from ...

G Protein‐Coupled receptors and heterotrimeric G proteins as cancer drivers [PDF]

open access: yesFEBS Letters, 2020
G protein‐coupled receptors (GPCRs) and heterotrimeric G proteins play central roles in a diverse array of cellular processes. As such, dysregulation of GPCRs and their coupled heterotrimeric G proteins can dramatically alter the signalling landscape and functional state of a cell.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Molecular architecture of Gαo and the structural basis for RGS16-mediated deactivation [PDF]

open access: yes, 2008
Heterotrimeric G proteins relay extracellular cues from heptahelical transmembrane receptors to downstream effector molecules. Composed of an α subunit with intrinsic GTPase activity and a βγ heterodimer, the trimeric complex dissociates upon receptor ...

Diabetıc Cardiomyopathy And G Protein

open access: yesVan Tıp Dergisi, 2019
Diabetes mellitus (DM) is one of the most important disease in the modern society and represents not only a medical but also social problem. Cardiovascular disease is the primary cause of death in people with either type 1 or type 2 diabetes.

Interaction of class A G protein-coupled receptors with G proteins.

open access: yesActa Biochimica Polonica, 2004
A model for interaction of class A G protein-coupled receptor with the G protein G(alpha) subunit is proposed using the rhodopsin-transducin (RD/Gt) prototype. The model combines the resolved interactions/distances, essential in the active RD*/Gt system, with the structure of Gt(alpha) C-terminal peptide bound to RD* while stabilizing it.

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Homologous and unique G protein alpha subunits in the nematode Caenorhabditis elegans [PDF]

open access: yes, 1991
A cDNA corresponding to a known G protein alpha subunit, the alpha subunit of Go (Go alpha), was isolated and sequenced. The predicted amino acid sequence of C. elegans Go alpha is 80-87% identical to other Go alpha sequences.

Nutritional characteristics of selected insects in Uganda for use as alternative protein sources in food and feed [PDF]

open access: yes, 2020
Open Access Journal; Published online: 18 Dec 2019Insects are potential ingredients for animal feed and human food. Their suitability may be influenced by species and nutritional value.
