products description :
Description: Paraoxonase-2 Human Recombinant is expressed in E Coli having a molecular weight of 43.5 kDa and fused to an amino terminal hexahistidine tag.The PON2 purified by proprietary chromatographic techniques. Introduction: Paraoxonase 2 (PON2) is a member of a multigene family whose genes share 65% identity at the amino acid level, and is expressed in a variety of tissues, including the pancreas. PON2 overexpression has been shown to lower the intracellular oxidative state and reduce the cells ability to oxidize LDL. PON2 is therefore implicated in the modulation of oxidative stress.

ncbi summary :
This gene encodes a member of the paraoxonase gene family, which includes three known members located adjacent to each other on the long arm of chromosome 7. The encoded protein is ubiquitously expressed in human tissues, membrane-bound, and may act as a cellular antioxidant, protecting cells from oxidative stress. Hydrolytic activity against acylhomoserine lactones, important bacterial quorum-sensing mediators, suggests the encoded protein may also play a role in defense responses to pathogenic bacteria. Mutations in this gene may be associated with vascular disease and a number of quantitative phenotypes related to diabetes. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
uniprot summary :
PON2: Capable of hydrolyzing lactones and a number of aromatic carboxylic acid esters. Has antioxidant activity. Is not associated with high density lipoprotein. Prevents LDL lipid peroxidation, reverses the oxidation of mildly oxidized LDL, and inhibits the ability of MM-LDL to induce monocyte chemotaxis. Belongs to the paraoxonase family. 3 isoforms of the human protein are produced by alternative splicing. Protein type: EC 3.1.1.81; Motility/polarity/chemotaxis; EC 3.1.1.2; Hydrolase. Chromosomal Location of Human Ortholog: 7q21.3. Cellular Component: mitochondrion; lysosome; extracellular region; plasma membrane; nucleus. Molecular Function: identical protein binding; arylesterase activity; metal ion binding. Biological Process: response to oxidative stress; aromatic compound catabolic process
