May play a role in lipid droplet formation. May modulate triglyceride levels. a primary alcohol + NAD(+) = an aldehyde + H(+) + NADH a secondary alcohol + NAD(+) = a ketone + H(+) + NADH Expressed in the intestine and vulva. Not expressed in embryos. Viable, but intestinal cells contain lipid droplets that are reduced in size and that contained a reduced amount of triglycerides as compared to wild-type. Belongs to the short-chain dehydrogenases/reductases (SDR) family.
