CELE_R12A1.4, ges1, R12A1.4

ges-1 encodes a gut-specific type B carboxylesterase; by homology, GES-1 hydrolyzes carboxylic ester substrates to yield an alcohol and a carboxylic anion, however, loss of GES-1 activity via mutation or RNAi does not result in any obvious abnormalities; GES-1 is expressed solely in the intestinal, or E, lineage from the 4 E-cell stage of gut development through adulthood; GES-1 contains a C-terminal endoplasmic reticulum (ER) retention sequence, KDEL, which suggests that it localizes to the ER lumen; GES-1 expression in the gut appears to be positively regulated by ELT-2, a gut-specific GATA-type transcription factor expressed throughout the C. elegans life cycle and essential for normal gut development.
