Thought to act as a glyoxalase. May remove methylglyoxal from mitochondrial proteins. Has roles in reducing oxidative stress and increasing lifespan. Expressed in the following tissues in both larvae and adults: pharynx, pharyngeal-intestinal valve, intestine, anal sphincter, vulval muscle, seam cells and the nervous system. Expression increases from day 1 to day 12 but activity decreased 10-fold during this period indicating that post translational modification is operational. Belongs to the glyoxalase I family.
