FAMILY

paraoxonase family

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	extracellular
text	secreted by the liver and transported in the blood complexed to HDL

basic FUNCTION	hydrolyzing the toxic metabolites of a variety of organophosphorous insecticides
	may mediate an enzymatic protection of low density lipoproteins against oxidative modification
	leading to anti-atherogenic effects by specifically binding to macrophage binding sites
	having antioxidative and atheroprotective role
	high-density lipoprotein (HDL)-bound enzyme that exerts antiatherogenic properties by protecting low-density lipoprotein (LDL)-cholesterol from oxidative modification

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

detoxification

PATHWAY

metabolism

signaling

a component

MPO, PON1, and high-density lipoprotein bind to one another, forming a ternary complex, wherein PON1 partially inhibits MPO activity, while MPO inactivates PON1

INTERACTION

DNA

RNA

small molecule

protein

cell & other

binding to macrophage

REGULATION

repressed by

bile acids through the actions of NR1H4 and FGF19

Variant & Polymorphism SNP , other	Arg192 allele increased survival at extreme advanced age
	polymorphism 192Q/R, 55M/L,and promoter variant 107C/T increases protection against coronary artery disease
	-161[C/T] SNP in creasing the risk of Alzheimer
	Q192R polymorphism increasing the risk of sporadic amyotrophic lateral sclerosis and associated with stroke and myocardial infarction
	variants at codon 192 impact on the probability of attaining longevity
	Q192R polymorphism could be an important risk factor for stroke
