Also known as CE-2iCECES2A1
Summary
CES2 (carboxylesterase 2, HGNC:1864) is a protein-coding gene on chromosome 16q22.1, encoding Cocaine esterase (O00748). Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs.
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. The protein encoded by this gene is the major intestinal enzyme and functions in intestine drug clearance. Alternatively spliced transcript variants have been found for this gene.

Subcellular location. Endoplasmic reticulum lumen.
Tissue specificity. 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.
Post-translational modifications. Glycosylated.
Miscellaneous. Probably produced by alternative initiation of isoform 1. Does not contain a signal peptide. The biological function of the extra amino acids in the N-terminus remains to be determined. Probably produced by alternative initiation of isoform 2. Does not contain a signal peptide.

Reactome pathways and GO biological processes over-represented among this gene’s 83 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
