SOD2

  • Official Full Name

    superoxide dismutase 2, mitochondrial

  • Overview

    This gene is a member of the iron/manganese superoxide dismutase family. It encodes a mitochondrial protein that forms a homotetramer and binds one manganese ion per subunit. This protein binds to the superoxide byproducts of oxidative phosphorylation and converts them to hydrogen peroxide and diatomic oxygen. Mutations in this gene have been associated with idiopathic cardiomyopathy (IDC), premature aging, sporadic motor neuron disease, and cancer. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

What is SOD2 protein?

SOD2 (superoxide dismutase 2) gene is a protein coding gene which situated on the long arm of chromosome 6 at locus 6q25. The encoded protein is a member of the iron/manganese superoxide dismutase family. It encodes a mitochondrial protein that forms a homotetramer and binds one manganese ion per subunit. This protein binds to the superoxide byproducts of oxidative phosphorylation and converts them to hydrogen peroxide and diatomic oxygen. The SOD2 protein is consisted of 222 amino acids and its molecular mass is approximately 27.8 kDa.

What is the function of SOD2 protein?

SOD2 can catalyze the reaction of superoxide anion free radicals with water to generate hydroperoxide and oxygen, thereby reducing the concentration of superoxide free radicals in cells and alleviating oxidative stress damage. By scavenging superoxide free radicals produced within mitochondria, SOD2 protects mitochondrial membranes, proteins, and DNA from oxidative damage. SOD2 also reduces inflammation. Normal SOD2 activity can maintain cell stability and inhibit cell mutation and malignant transformation.

SOD2 Related Signaling Pathway

The signaling pathway related to SOD2 protein involves many aspects, including ROS/ oxidative stress signaling pathway, PI3K/AKT signaling pathway, MAPK signaling pathway, Nrf2/ARE signaling pathway and NF-κB signaling pathway. These signaling pathways interact to jointly regulate the expression and activity of SOD2 and influence the cell response to oxidative stress.

SOD2 Related Diseases

Mutations in this gene have been associated with idiopathic cardiomyopathy (IDC), premature aging, sporadic motor neuron disease. The dysfunction of SOD2 may lead to increased intracellular oxidative stress, which in turn is involved in the occurrence and development of some neurodegenerative diseases (such as Alzheimer's disease, Parkinson's disease), nervous system damage, and lung diseases. In addition, some studies have found that the expression level of SOD2 is associated with tumorigenesis and treatment response.

Bioapplications of SOD2

SOD2 protein has many applications in the field of biology, involving cellular oxidative stress, mitochondrial function, neurodegenerative diseases, tumorigenesis and development. The in-depth study of it is helpful to reveal the pathogenesis of related diseases and provide new targets and strategies for the treatment of diseases.

Case study 1: Diego R Coelho, 2022

The dichotomous behavior of superoxide dismutase-2 (SOD2) in cancer biology has long been acknowledged and more recently linked to different posttranslational forms of the enzyme. However, a distinctive activity underlying its tumor-promoting function is yet to be described. Western blots confirming the subcellular localization of SOD2 were performed and a PicoProbe Formaldehyde Assay Kit (BioVision, K805) was used to quantify formaldehyde (HCHO) produced by demethylase activity of SOD2 and so on.

Here, the researchers report that acetylation, one of such posttranslational modifications (PTMs), increases SOD2 affinity for iron, effectively changing the biochemical function of this enzyme from that of an antioxidant to a demethylase. Acetylated, iron-bound SOD2 localizes to the nucleus, promoting stem cell gene expression via removal of suppressive epigenetic marks such as H3K9me3 and H3K927me3. Together, the results provide evidence in support of an acetylation-dependent nucleus-specific function of SOD2 associated with the emergence of more tumorigenic and metastatic cancer cell phenotypes.

Case study 2: Atinuke Dosunmu-Ogunbi, 2022

Sickle cell disease (SCD) is a genetic red blood cell disorder characterized by increased reactive oxygen species (ROS) and a concordant reduction in antioxidant capacity in the endothelium. Superoxide dismutase 2 (SOD2) is a mitochondrial-localized enzyme that catalyzes the dismutation of superoxide to hydrogen peroxide. Decreased peripheral blood expression of SOD2 is correlated with increased hemolysis and cardiomyopathy in SCD.

To investigate the impact of decreased SOD2 expression in the endothelium, SOD2 was knocked down in human pulmonary microvascular endothelial cells (hPMVECs). The researchers found that SOD2 deficiency in hPMVECs results in endothelial cell dysfunction, including reduced cellular adhesion, diminished migration, integrin protein dysregulation, and disruption of permeability. Furthermore, they uncover that SOD2's inability to facilitate dimerization. These results demonstrate that endothelial cells are deficient in SOD2 expression in SCD patients and suggest a novel pathway for SOD2 in regulating fibronectin processing.

What therapeutic strategies target SOD2 for disease treatment? 11/06/2020

Several approaches have been explored to enhance SOD2 activity as a potential therapeutic strategy. These include the use of small molecule activators, such as resveratrol and melatonin, which can upregulate SOD2 expression and improve cellular antioxidant defense. Additionally, gene therapy approaches aiming to increase SOD2 levels or activity have shown promise in preclinical studies.

How does SOD2 contribute to cellular senescence and aging? 10/23/2020

As cells age, the expression and activity of SOD2 decline, resulting in increased levels of reactive oxygen species (ROS) and oxidative damage. The accumulation of ROS can promote cellular senescence, a state of irreversible growth arrest. SOD2 plays a crucial role in mitigating ROS-mediated DNA damage and preserving cellular integrity, thus influencing the aging process.

How is the expression of SOD2 regulated? 09/25/2020

The expression of SOD2 is regulated by various transcription factors, including nuclear factor erythroid 2-related factor 2 (NRF2) and forkhead box O3 (FOXO3). These transcription factors bind to the promoter region of the SOD2 gene and initiate its transcription. Additionally, post-translational modifications, such as acetylation and phosphorylation, can also modulate the activity and stability of SOD2.

What is the significance of SOD2 polymorphisms in disease susceptibility? 02/28/2019

Certain genetic variations or polymorphisms in the SOD2 gene have been associated with altered enzyme activity and increased susceptibility to certain diseases, including neurodegenerative disorders, cardiovascular diseases, and cancer. These polymorphisms can affect the antioxidant capacity of SOD2, leading to an imbalance between reactive oxygen species generation and scavenging, thereby contributing to disease pathogenesis.
