Activity summary

Nitrotyrosine also known as 3-nitrotyrosine is a marker for nitrosative stress and oxidative damage. It comes from the nitration of tyrosine an amino acid primarily through the action of reactive nitrogen species. Nitrotyrosine can be found in proteins and its molecular mass varies depending on the protein context. It is present across various tissues and fluid samples within the body particularly where high oxidative stress occurs.

Biological function summary

Nitrotyrosine acts as an indicator of cellular damage and protein modification due to stress conditions. When proteins have nitrotyrosine residues their function might change which can lead to cellular signaling disruption. Nitrotyrosine is not usually part of a specific complex but it affects proteins and enzymes by altering their activity and stability contributing to larger stress response mechanisms.

Pathways

Proteins modified by nitrotyrosine are involved in cellular pathways related to oxidative stress and inflammation. Particularly pathways like the nitric oxide synthase pathway and the inflammatory response pathway include nitrotyrosine-modified proteins. It is related to proteins such as nitric oxide synthase (NOS) and superoxide dismutase (SOD) important in managing oxidative balance and stress responses in cells.

Associated diseases and disorders

Nitrotyrosine is significantly linked to diseases related to oxidative stress such as cardiovascular disease and neurodegenerative disorders. These conditions often have increased levels of nitrotyrosine indicating heightened oxidative damage. Through these diseases nitrotyrosine connects with proteins like amyloid-beta in neurodegenerative disorders and endothelial nitric oxide synthase (eNOS) in cardiovascular diseases reflecting the impact of oxidative stress on these proteins.
