Peroxiredoxin-5 (PRDX5), mitochondrial is a protein that in humans is encoded by the PRDX5 gene, located on chromosome 11.[5]

This gene encodes a member of the six-member peroxiredoxin family of antioxidant enzymes. Like the other five members, PRDX5 is widely expressed in tissues but differs by its large subcellular distribution.[6] In human cells, it has been shown that PRDX5 can be localized to mitochondria, peroxisomes, the cytosol, and the nucleus.[7] Human PRDX5 is identified by virtue of the sequence homologies to yeast peroxisomal antioxidant enzyme PMP20.[6][8]

Biochemically, PRDX5 is a peroxidase that can use cytosolic or mitochondrial thioredoxins to reduce alkyl hydroperoxides or peroxynitrite with high rate constants in the 106 to 107 M−1s−1 range, whereas its reaction with hydrogen peroxide is more modest, in the 105 M−1s−1 range.[7] So far, PRDX5 has been shown to be a cytoprotective antioxidant enzyme that inhibits endogenous or exogenous peroxide accumulation.[7]

Structure

[edit]

According to its amino acid sequence, this 2-Cys peroxiredoxin, PRDX5, is the most divergent isoform among mammalian peroxiredoxins, processing only 28% to 30% sequence identity with typical 2-Cys and 1-Cys peroxiredoxins.[9] The divergent amino acid sequence of this atypical peroxiredoxin is reflected in its unique crystal structure. The typical peroxiredoxin is composed of a thioredoxin domain and a C-terminal, whereas PRDX5 has an N-terminal domain and a unique alpha helix replaces a loop structure in the typical thioredoxin domain.[7] In addition, typical 2-Cys or 1-Cys peroxiredoxins are associated as anti-parallel dimers via linkage of two beta-7-strands, whereas a PRDX5 dimer is formed by close contact between an alpha-3-helix of one molecule and an alpha-5-helix from the other molecule.[7]

Function

[edit]

As a peroxiredoxin, PRDX5 has antioxidative and cytoprotective functions during oxidative stress. Overexpression of human PRDX5 has been shown to inhibit peroxide accumulation induced by TNF-alpha, PDGF, and p53 in NIH3T3 and HeLa cells and reduce cell death by exogenous peroxide in multiple organelles of CHO, HT-22, and human tendon cells.[6][10][11][12][13] Meanwhile, reduced expression of PRDX5 induces cell susceptibility to oxidative damage and etoposide, doxorubicin, MPP+, and peroxide-induced apoptosis.[14][15][16][17] In addition, expressing human PRDX5 in other organisms or tissues such as yeast, mouse brain, and Xenopus embryos also leads to protection against oxidative stress.[18][19][20] PRDX5 in Drosophila melanogaster has been shown to promote longevity in addition to antioxidant activity.[21]

Clinical significance

[edit]

By examining 98 stroke patients, Kunze et al. showed an inverse correlation between stroke progression and PRDX5 concentration, suggesting that plasma PRDX5 can be a potential biomarker of inflammation in acute stroke.[22] In human breast cancer cells, knockdown of transcription factor, GATA1, led to increased expression of PRDX5 and inhibition of apoptosis.[10] A substantial increase in PRDX5 expression has been observed in astrocytes in multiple sclerosis lesion.[23] PRDX5 has also been identified as a candidate risk gene for the inflammatory disease, sarcoidosis.[24]

Interactions

[edit]

Transcription factor GATA-binding protein 1 can bind to the PRDX5 gene and lead to increased expression of PRDX5.[10] PRDX5 has been shown to physically interact with PRDX1, PRDX2, PRDX6, SOD1, and PARK7 in at least two independent high-throughput proteomic analyses.[25]
