Target Background

(From Uniprot)
May act as an oxidative stress mediator by inhibiting thioredoxin activity or by limiting its bioavailability. Interacts with COPS5 and restores COPS5-induced suppression of CDKN1B stability, blocking the COPS5-mediated translocation of CDKN1B from the nucleus to the cytoplasm. Inhibits the proteasomal degradation of DDIT4, and thereby contributes to the inhibition of the mammalian target of rapamycin complex 1 (mTORC1) (By similarity). Functions as a transcriptional repressor, possibly by acting as a bridge molecule between transcription factors and corepressor complexes, and over-expression will induce G0/G1 cell cycle arrest. Required for the maturation of natural killer cells. Acts as a suppressor of tumor cell growth (By similarity).

  1. This study found that acupuncture treatment alleviated cognitive decline and hippocampal neuronal death by inhibiting cerebral oxidative stress and inflammation, which was probably through downregulating TXNIP expression. PMID: 29110407
  2. TXNIP contributes to the dysregulation of tubular autophagy and mitophagy in diabetic nephropathy through activation of the mTOR signaling pathway. PMID: 27381856
  3. results demonstrated, for the first time, that SalA protects against HFD-induced NAFLD by ameliorating hepatic lipid accumulation and inflammation, and these protective effects may partially due to regulation of the TXNIP/NLRP3 and TXNIP/ChREBP pathways. PMID: 27345365

  5. TXNIP level is also significantly upregulated in the diabetic rat retina in vivo and induces radial glial fibrillary acidic protein expression, a marker for Muller glia activation, and the formation of LC3BII puncta, which are prevented by intravitreal injection of TXNIP siRNA. PMID: 28492550
  6. histone acetylation serves as a key regulator of glucose-induced increase in TXNIP gene expression PMID: 27989964

  8. Down-regulation of TXNIP or inhibition of NLRP3 contributed to the suppression of NLRP3 inflammasome activation, inflammation, and re-balanced lipid metabolism. In contrast, overexpression of TXNIP or agonism of NLRP3 exacerbated the cellular damage induced by sodium palmitate. PMID: 26133299
