Thioredoxin and thioredoxin binding protein 2 in the liver [PDF]
IUBMB Life, 2008 AbstractThioredoxin (TRX) is a 12‐kDa protein with redox‐active dithiol in the active site ‐Cys‐Gly‐Pro‐Cys‐ and constitutes a major thiol reducing system. TRX protects cells from stress‐induced damage through antioxidative, antiapoptotic, and anti‐inflammatory effect.

NTRC Effects on Non-Photochemical Quenching Depends on PGR5
Antioxidants, 2021 Non-photochemical quenching (NPQ) protects plants from the detrimental effects of excess light. NPQ is rapidly induced by the trans-thylakoid proton gradient during photosynthesis, which in turn requires PGR5/PGRL1-dependent cyclic electron flow (CEF ...

Crystal structure of the human thioredoxin reductase–thioredoxin complex [PDF]
Nature Communications, 2011 Thioredoxin reductase 1 (TrxR1) is a homodimeric flavoprotein crucially involved in the regulation of cellular redox homeostasis, growth, and differentiation. Its importance in various diseases makes TrxR1 a highly interesting drug target. Here we present the first crystal structures of human TrxR1 in complex with its substrate thioredoxin (Trx).

Frontiers in Cellular and Infection Microbiology, 2017 Microbes employ the thioredoxin system to defend against oxidative stress and ensure correct disulfide bonding to maintain protein function. Listeria monocytogenes has been shown to encode a putative thioredoxin, TrxA, but its biological roles and ...

Using Resurrected Ancestral Proviral Proteins to Engineer Virus Resistance
Cell Reports, 2017 Proviral factors are host proteins hijacked by viruses for processes essential for virus propagation such as cellular entry and replication. Pathogens and their hosts co-evolve. It follows that replacing a proviral factor with a functional ancestral form

Ezrin: a regulator of actin microfilaments in cell junctions of the rat testis
Asian Journal of Andrology, 2015 Ezrin, radixin, moesin and merlin (ERM) proteins are highly homologous actin-binding proteins that share extensive sequence similarity with each other.

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid
Angewandte Chemie, EarlyView.The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐

Are sperm capacitation and apoptosis the opposite ends of a continuum driven by oxidative stress?
Asian Journal of Andrology, 2015 This chapter explores the possibility that capacitation and apoptosis are linked processes joined by their common dependence on the continued generation of reactive oxygen species (ROS).

In silico analysis of thioredoxins and glutaredoxins
, 2005 Thioredoxins (TRXs) and glutaredoxins (GRXs) are ubiquitous small redox proteins belonging to the thioredoxin (TRX) superfamily. They regulate several cellular functions via mediating a dithiol/disulphide exchange in target proteins.
