Glutathione peroxidase 1 is regulated by the c-Abl and Arg tyrosine kinases.

Abstract excerpt

The c-Abl and Arg tyrosine kinases are activated in the cellular response to oxidative stress. The present studies demonstrate that c-Abl and Arg associate with glutathione peroxidase 1 (GPx1) and that this interaction is regulated by intracellular oxidant levels. The c-Abl and Arg SH3 domains bind directly to a proline-rich site in GPx1 at amino acids 132-145. GPx1 also functions as a substrate for c-Abl- and...
