Anti-Peroxiredoxin 4/PRDX4 Antibody Picoband® fluoro488 Vervoeging

PRDX4 (peroxiredoxin 4) also known as AOE37-2. The protein encoded by this gene is an antioxidant enzyme and belongs to the peroxiredoxin family. Functional analysis showed that  PRDX4  protects glutamine synthetase from inactivation. Yeast 2-hybrid, immunoprecipitation, and immunoblot analyses indicated that  PRDX4  and PRDX1 are capable of homodimerization and heterodimerization with each other but not with the mitochondrial PRDX3. Gel mobility shift and immunoblot analysis found that  PRDX4  depletes NFKB binding activity together with a reduction in the amounts of p50, p65, and phosphorylated IKBA, as well as a reduction in the expression of HIV-1 viral proteins. Expression of  PRDX4, alone or with PRDX1, increased the resistance of yeast cells to oxidant-induced toxicity.  Jin et al. (1997) suggested  PRDX4  modulates IKBA phosphorylation in the cytoplasm and thus affects a peroxiredoxin-dependent redox step.
