Nucleoredoxin (NXN)

Target
NXN
Molecular classification
Enzyme (specifically, oxidoreductase), Thioredoxin family protein
01

Overview

Nucleoredoxin (NXN) is a thiol-oxidoreductase enzyme of the thioredoxin family ubiquitously expressed in mammalian cells, shuttling between the cytosol and nucleus. Its redox-dependent interactions regulate signaling pathways such as WNT/β-catenin (via disheveled/DVL), Toll-like receptor 4/MYD88/NF-κB, and protein phosphatase 2A (PP2A). NXN participates in critical processes including cell cycle control, cell proliferation, neuronal development, glycolysis, cytoskeletal regulation, immune responses, and organogenesis. Dysregulation or genetic variants of NXN are implicated in cancer, metabolic and neurodegenerative diseases, and other systemic pathologies. As a central hub for cellular redox signaling, NXN is an important candidate for therapeutic targeting and fundamental cell biology research

Safety considerations

As NXN is a master regulator of cellular redox homeostasis, systemic inhibition or activation could disrupt redox balance, potentially affecting vital signaling pathways and leading to adverse effects or unexpected toxicity in targeted therapies
06

Interacting drugs

None reported in the literature; as of now, there are no approved drugs or clinical candidates specifically targeting Nucleoredoxin
07

Biomarkers

None specifically validated for patient selection or efficacy monitoring in clinical use; however, altered NXN expression or activity might serve as research biomarkers for redox imbalance or related pathologies
