Anti-peroxiredoxin 2/PRDX2 Antibody Picoband® Fluoro550 Conjugated

PRDX2 (peroxiredoxin 2) also known as NKEFB, PRP, PRX2, PRXII or TPX1, is a?protein?that in humans is encoded by the?PRDX2?gene. This gene encodes a member of the peroxiredoxin family of antioxidant?enzymes, which reduce hydrogen peroxide and alkyl hydroperoxides.?The encoded protein may play an antioxidant protective role in cells, and may contribute to the antiviral activity of CD8 (+) T-cells. This protein may have a proliferative effect and play a role in cancer development or progression. The?Prdx2?-/- mice were healthy in appearance and fertile. Choi et al. (2005) ?demonstrated that?PRDX2?is a negative regulator of PDGF signaling. Prx II deficiency results in increased production of peroxide, enhanced activation of PDGF receptor and phospholipase C-gamma-1, and subsequently increased cell proliferation and migration in response to PDGF. PRX2 accounted for about half of the thioredoxin activity in parasite extracts, and PRX2 expression was increased in the presence of chloroquine, regardless of P. falciparum strain susceptibility to the drug.

After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
