Anti-Peroxiredoxin 5/PRDX5 Antibody Picoband®

PRDX5 (peroxiredoxin 5) also known as  AOEB166, ACR1, B166, MGC117264, MGC142283, MGC142285, PLP, PMP20,   PRDX6, PRXV, SBBI10, is a member of the peroxiredoxin family and may play an antioxidant protective role in various tissues under nonpathologic conditions and during inflammatory processes. The PRDX5 gene is mapped on 11q13.1. PRDX5  displays mitochondrial presequence features and has 3 cysteines implicated in antioxidant activity and a C-terminal SQL peroxisomal targeting sequence. Northern blot analysis revealed ubiquitous expression of a 1.0-kb  PRDX5  transcript in tissues and cell lines.  Functional analysis showed that  PRDX5  has antioxidant activity equivalent to that of CAT. While  PRDX5  was localized to fibroblasts in normal tendon, it was localized to fibroblasts and endothelial cells in degenerative tendon. PRDX5  mRNA and protein levels increased at 12 hours, and the increase in  PRDX5  expression correlated with reduced peroxide levels. PRDX5  plays a protective role against oxidative stress in human cartilage.
