GeneID: 162


Common Name: PON1 Type: Gene
Chromosome: 7 (NC_000007.14) Locus: NG_008779.1 (PON1)
HUGO Symbol: PON1 Full Name: paraoxonase 1
Exons: 9 Introns: 8

The encoded protein belongs to the family of human serum paraoxonases, which are involved in the hydrolysis of a wide range of organophosphorous compounds, including paraoxon, neurotoxins and insecticides. It exhibits antioxidant properties in lipid metabolism via the removal of the biologically active products of lipid peroxidation (oxidative damage of lipids). It also exhibits antiatherogenic properties as PON1 deficiency in mice was shown to enhance lipoprotein oxidation and atherosclerosis development. Polymorphisms in this gene associated with risk for stroke in individuals with sickle cell disease.

Synonyms: ESA , PON , MVCD5 , arylesterase 1 , esterase A
