Supplementary information

The 'MSRA' protein also known as Methionine Sulfoxide Reductase A is an enzyme that catalyzes the reduction of oxidized methionine residues within proteins. MSRA primarily operates by converting methionine sulfoxide back to methionine therefore playing a critical role in the repair of proteins that have been damaged by oxidative stress. The molecular weight of the MSRA protein typically falls around 25 kDa. Expression of MSRA is found in various tissues with notable levels in the liver kidney brain and heart.
Biological function summary

MSRA contributes to cellular defense against oxidative damage by restoring the normal function of proteins compromised by reactive oxygen species. This enzyme does not form part of a larger complex but acts independently on its substrate. It plays an important role in maintaining protein structure and function under stressful conditions such as during immune responses and aging.

Pathways

MSRA functions are important in the oxidative stress response and redox signaling pathways. It works alongside other antioxidant proteins like Methionine Sulfoxide Reductase B (MSRB) to maintain cellular homeostasis. The supportive roles within these pathways enhance the stability of cell environments protecting the cells from damage induced by external and internal oxidative agents.

MSRA is linked to conditions characterized by increased oxidative stress such as Alzheimer's disease and cardiovascular diseases. Reduced activity of MSRA correlates with higher oxidative stress levels leading to protein dysfunction within the brain and heart. The connections to these diseases often involve interactions with other oxidative stress-targeted proteins like superoxide dismutase and catalase highlighting MSRA's role in maintaining cellular integrity under pathophysiological conditions.
