"WebbHere, we show that nitration of a single tyrosine residue on a small proportion of 90-kDa heat-shock protein (Hsp90), is sufficient to induce motor neuron death by the P2X7 receptor-dependent activation of the Fas pathway. Nitrotyrosine at position 33 or 56 stimulates a toxic gain of function that turns Hsp90 into a toxic protein. " - Protein tyrosine nitration

WebbThere are two additional pathways of action by which peroxynitrite/oxidative stress can act to lower signaling via the cGMP/protein kinase G. Protein kinase G has been shown undergo peroxynitrite-mediated high level tyrosine nitration on specific residue, leading to inactivation of the enzyme [114–117]. WebbHowever glial fibrillary acidic protein contained 3-nitrotyrosine residues prior to ischaemia-reperfusion, and the amount of nitrated tyrosine residues in total glial fibrillary acidic protein did not increase significantly during reperfusion, therefore it was not possible to draw conclusions about the role of peroxynitrite in nerve reperfusion injury.
