Anti-Peroxiredoxin 3/PRDX3 Antibody Picoband® Fluoro488 Conjugated

PRDX3 (peroxiredoxin 3) also known as AOP-1, MER5, SP-22 or PRX3, is localized exclusively in mitochondria. The deduced 256-amino acid human AOP1 protein shares 86% amino acid sequence similarity with mouse Aop1, and significant similarity with both the human proliferation-associated gene A product and the mouse stress-induced peritoneal macrophage protein Msp23.  The PRDX3 gene is mapped on 10q26.11. Expression of  PRDX3  is induced by MYC and is reduced in c-myc -/- cells. Chromatin immunoprecipitation analysis spanning the entire  PRDX3  genomic sequence revealed that MYC binds preferentially to a 930-bp region surrounding exon 1. Results using mitochondria-specific fluorescent probes demonstrated that  PRDX3  is essential for maintaining mitochondrial mass and membrane potential in transformed rat and human cells. These data provided evidence that  PRDX3  is a MYC target gene that is required to maintain normal mitochondrial function.
