Summary
Enables carboxylesterase activity. Is expressed in adult head; larval muscle system; larval somatic muscle cell; and organism. Human ortholog(s) of this gene implicated in colorectal cancer and gastrointestinal system cancer. Orthologous to several human genes including CES1 (carboxylesterase 1); CES2 (carboxylesterase 2); and CES3 (carboxylesterase 3). [provided by Alliance of Genome Resources, Jan 2025]
