Carboxylesterase 2 (CES2)
Carboxylesterase 2 (CES2) is a member of the carboxylesterase family and belongs to the multigene family. Carboxylesterase 2 is responsible for the hydrolysis of ester- and amide-bond-containing drugs such as cocaine and beroin. It also serves to hydrolyze long-chain fatty acid esters and thioesters. It is speculated that carboxylesterases may play a role in lipid metabolism and the blood-brain barrier system and together with isform 1, are a serine esterase involved in both drug metabolism and activation. Human carboxylesterase 2 is commonly expressed in tumor tissues and irinotecan, a topoisomerase I inhibitor commonly used in the treatment of many solid tumors.

Entrez Gene summary for CES2:
This CES2 gene encodes a member of the carboxylesterase large family. The family members are responsible for the hydrolysis or transesterification of various xenobiotics, such as cocaine and heroin, and endogenous substrates with ester, thioester, or amide bonds. They may participate in fatty acyl and cholesterol ester metabolism, and may play a role in the blood-brain barrier system. The protein encoded by this CES2 gene is the major intestinal enzyme and functions in intestine drug clearance. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Oct 2010]
OMIM - description for Carboxylesterase 2:
Carboxylesterases (CESs; EC 22.214.171.124) hydrolyze ester groups of drugs and toxins. CES2 specifically catalyzes the hydrolysis of the benzoyl group of cocaine and the acetyl groups of 4-methylumbelliferyl acetate, heroin, and 6-monoacetylmorphine. CES2 differs from another liver carboxylesterase, CES1 (114835), in drug ester substrate specificity. See 114835 for additional background information on carboxylesterases.
Wikipedia summary for Carboxylesterase 2:
Carboxylesterase 2 is an enzyme that in humans is encoded by the CES2 gene. It is a member of the alpha/beta fold hydrolase family.
Carboxylesterase 2 is a member of a large multigene family. The enzymes encoded by these genes are responsible for the hydrolysis of ester- and amide-bond-containing drugs such as cocaine and heroin. They also hydrolyze long-chain fatty acid esters and thioesters. The specific function of this enzyme has not yet been determined; however, it is speculated that carboxylesterases may play a role in lipid metabolism and/or the blood–brain barrier system. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.[

Cocaine + H2O = ecgonine methyl ester + benzoate.
Carboxylesterase 2 belongs to the type-B carboxylesterase/lipase family.
|Subcellular location:||Endoplasmic reticulum lumen|
Carboxylesterase 2 is preferentially expressed in intestine with moderate expression in liver. Within the intestine, highest expression is found in small intestine with lower expression in colon and rectum.

General information above from UniProt
Carboxylesterase 2 is involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Carboxylesterase 2 shows high catalytic efficiency for hydrolysis of cocaine, 4-methylumbelliferyl acetate, heroin and 6-monoacetylmorphine.
