Positive regulator of reactive oxygen-induced cell death. May be involved in the repression of the copper/zinc superoxide dismutase CSD1 and CSD2 that detoxify accumulating superoxide before the reactive oxygen species (ROS) can trigger a cell death cascade. LSD1 and LOL1 have antagonistic effects on CSD1 and CSD2 accumulation to regulate oxidative stress-induced cell death. Over-expression of LOL1 induces cell death. Sequencing errors.
