ab109506 was shown to react with PRDX1 in wild-type U-2 OS cells in Immunocytochemistry with loss of signal observed in a PRDX1 knockout cell line. Wild-type and knockout cells were mixed and pelleted at a 1 : 1 ratio on coverslips. The cells were fixed with then permeabilized with and then blocked with 1/10000. The cells were then incubated with ab109506 at 1/250. 1/5000 would be better dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a secondary antibody to (Alexa Fluor® 555) at 0.5 μg/ml. Acquisition of the green (wild-type), red (antibody staining) and far-red (knockout) channels was performed. Representative grayscale images of the red channel are shown. Wild-type and knockout cells are outlined with yellow and magenta dashed line, respectively. Schematic representation of the mosaic strategy used is shown on the bottom-right panel. Image was acquired with a Zeiss(LSM-880).

Supplementary information

Peroxiredoxin 1 also known as PAG plays an important role as an antioxidant enzyme. It is part of the peroxiredoxin family with a molecular mass of around 22 kDa. This protein helps reduce hydrogen peroxide and organic hydroperoxides to water and corresponding alcohols using reducing equivalents provided by thiol-containing donor molecules. Peroxiredoxin 1/PAG expresses widely in human tissues and cells including liver and erythrocytes reflecting its involvement in cellular redox regulation.
Biological function summary

Peroxiredoxin 1 helps maintain cellular homeostasis by protecting cells from oxidative stress. It forms homodimers or interacts with other proteins to propagate cellular responses to changes in redox state. As an important member of the antioxidant defense mechanism it contributes to cellular signaling through modulation of hydrogen peroxide signaling pathways. The protein also plays a role in cell proliferation and apoptosis making it significant for cellular health and disease prevention.

Pathways

Peroxiredoxin 1 participates in critical processes such as the MAPK signaling and TGF-beta pathways. It interacts with MAPK-related proteins influencing cell survival and growth. Peroxiredoxin 1 indirectly modulates downstream signaling molecules that contribute to cellular responses. In these pathways the protein's antioxidant properties allow regulation of reactive oxygen species levels which directly affect cellular signaling cascades.

Peroxiredoxin 1 is relevant to cancer and neurodegenerative disorders. Overexpression or misregulation of this protein has been linked to various cancers where it potentially interacts with oncogenic proteins like c-Myc to promote tumor progression. Additionally abnormal levels of Peroxiredoxin 1 associate with neurodegenerative diseases as oxidative stress is a common factor in their pathology. These connections suggest the protein as a promising target in therapeutic interventions for these diseases.

Target data

Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides and as sensor of hydrogen peroxide-mediated signaling events. Might participate in the signaling cascades of growth factors and tumor necrosis factor-alpha by regulating the intracellular concentrations of H(2)O(2) (PubMed : 9497357). Reduces an intramolecular disulfide bond in GDPD5 that gates the ability to GDPD5 to drive postmitotic motor neuron differentiation (By similarity).
