EG13909, also known as Es-31, is a carboxylesterase-like enzyme identified in mouse liver. It belongs to the type B carboxylesterase/lipase superfamily that hydrolyzes the carboxylic ester bonds. By sequence analysis it is most closely related to mouse CES-3 and is likely to be a microsomal enzyme. It has been suggested that EG13909 is expressed predominantly in male livers and might be regulated by growth hormone.
