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.
