Summaries for CES3 Gene

Entrez Gene Summary for CES3 Gene

  • This 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. This gene is expressed in several tissues, particularly in colon, trachea and in brain, and the protein participates in colon and neural drug metabolism. Multiple alternatively spliced transcript variants encoding distinct isoforms have been reported, but the biological validity and/or full-length nature of some variants have not been determined.[provided by RefSeq, Jun 2010]

GeneCards Summary for CES3 Gene

CES3 (Carboxylesterase 3) is a Protein Coding gene. Among its related pathways are E2F transcription factor network. GO annotations related to this gene include hydrolase activity and carboxylic ester hydrolase activity. An important paralog of this gene is CES2.

UniProtKB/Swiss-Prot for CES3 Gene

  • Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Shows low catalytic efficiency for hydrolysis of CPT-11 (7-ethyl-10-[4-(1-piperidino)-1-piperidino]-carbonyloxycamptothecin), a prodrug for camptothecin used in cancer therapeutics.
