The encoded protein is secreted into the bloodstream and associates with high-density lipoprotein (HDL). The protein also rapidly hydrolyzes lactones and can inhibit the oxidation of low-density lipoprotein (LDL), a function that is believed to slow the initiation and progression of atherosclerosis. Alternatively spliced variants which encode different protein isoforms have been described; however, only one has been fully characterized. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: Has low activity towards the organophosphate paraxon and aromatic carboxylic acid esters. Rapidly hydrolyzes lactones such as statin prodrugs (e.g. lovastatin). Hydrolyzes aromatic lactones and 5- or 6-member ring lactones with aliphatic substituents but not simple lactones or those with polar substituents. {ECO:0000269|PubMed:15772423}. |Arylesterase| |SGL| |3,4-dihydrocoumarin hydrolase activity| |coumarin catabolic process| |auxin catabolic process| |phenylpropanoid catabolic process| |phenylacetate catabolic process| |aryldialkylphosphatase activity| |auxin metabolic process| |acyl-L-homoserine-lactone lactonohydrolase activity| |negative regulation of superoxide anion generation| |toxin catabolic process| |arylesterase activity| |phenylpropanoid metabolic process| |coumarin metabolic process| |xenobiotic catabolic process| |lipoxygenase pathway| |hormone catabolic process| |regulation of superoxide anion generation| |toxin metabolic process| |benzene-containing compound metabolic process| |regulation of superoxide metabolic process| |negative regulation of reactive oxygen species metabolic process| |secondary metabolic process| |icosanoid metabolic process| |monocarboxylic acid catabolic process| |detoxification| |xenobiotic metabolic process| |fatty acid derivative metabolic process| |regulation of reactive oxygen species metabolic process| |cellular response to xenobiotic stimulus| |hormone metabolic process| |carboxylic acid catabolic process| |organic acid catabolic process| |response to xenobiotic stimulus| |dephosphorylation| |fatty acid metabolic process| |heterocycle catabolic process| |small molecule catabolic process| |aromatic compound catabolic process| |organic cyclic compound catabolic process| |response to toxic substance| |monocarboxylic acid metabolic process| |regulation of hormone levels| |intracellular membrane-bounded organelle| |protein homodimerization activity| |carboxylic acid metabolic process| |cellular lipid metabolic process| |oxoacid metabolic process| |organic acid metabolic process| |lipid metabolic process| |extracellular space| |small molecule metabolic process| |organic substance catabolic process| |cellular catabolic process| |extracellular region| \\ === CRISPR Data === No hits were found.
