  • IHC image of CSB-PA002309LA01HU diluted at 1:400 and staining in paraffin-embedded human liver cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

  1. Copper chaperone Atox-1 is involved in the induction of SOD3 in a monocyte cell line. PMID: 29168020
  2. Since full occupancy of the tetrahedral cavity is a common feature of all Atox1 dimeric structures obtained with other metal ions (Cu(+), Cd(2+), and Hg(2+)), we propose that in the case of platinum, where the occupancy is only 0.4, the remaining cavities are occupied by Cu(+) ions PMID: 27305454
  3. Data suggest that N-terminal segment of metal-binding domains (MBDs) 1-3 of ATOX1 interact with nucleotide-binding domain of ATP7B, thus physically coupling the domains involved in copper binding and those involved in ATP hydrolysis; interactions with MBDs 1-3 of ATOX1 activate ATP7B ATP hydrolysis.

  17. Cisplatin is one of the most used anticancer drugs. Its cellular influx and delivery to target DNA may involve the copper chaperone Atox1 protein. PMID: 25111319
  18. The data collected here shows that the Atox1 keeps its dimer nature also in the presence of the CTR1 c-terminal domain; however, two geometrical states are assumed by the Atox1. PMID: 24837030
  19. The Cu-binding motif in Atox1, as well as in target Cu-binding domains of ATP7A/B, consists of a MX1CXXC motif where X1 = T. PMID: 24824562
  20. Human Grx1 can catalyse reduction of Atox1 by glutathione but only in the presence of Cu(I). PMID: 24522867

  24. Atox1 contains positive residues that mediate membrane association and aid subsequent copper loading. PMID: 24036897

  29. different effects of ATX1 unfolding on Cu(I) affinity PMID: 23169585
  30. GSSG oxidizes copper-coordinating cysteines of Atox1 with formation of an intramolecular disulfide. GSH alone is sufficient to reduce the disulfide, restoring the ability of Atox1 to bind copper; glutaredoxin 1 facilitates this reaction when GSH is low PMID: 22648419
