Catalytic activity:Phosphatidylcholine + H(2)O = 1-acylglycerophosphocholine + a carboxylate.,Disease:Defects in PLA2G6 are a cause of neurodegeneration with brain iron accumulation (NBIA) [MIM:610217]. NBIA comprises a clinically and genetically heterogeneous group of disorders with high basal ganglia iron.,Disease:Defects in PLA2G6 are the cause of infantile neuroaxonal dystrophy 1 (INAD1) [MIM:256600]; also known as Seitelberger disease. Infantile neuroaxonal dystrophy (INAD) is a neurodegenerative disease characterized by pathologic axonal swelling and spheroid bodies in the central nervous system. Onset is within the first 2 years of life with death by age 10 years.,Disease:Defects in PLA2G6 are the cause of Karak syndrome [MIM:608395]. Karak syndrome is a neurologic disease characterized by early-onset progressive cerebellar ataxia, dystonia, spasticity, intellectual and features compatible with iron deposition in the putamen and substantia nigra.,Function:Catalyzes the release of fatty acids from phospholipids. It has been implicated in normal phospholipid remodeling, nitric oxide-induced or vasopressin-induced arachidonic acid release and in leukotriene and prostaglandin production. May participate in fas mediated apoptosis and in regulating transmembrane ion flux in glucose-stimulated B-cells.,Function:Isoform ankyrin-iPLA2-1 and isoform ankyrin-iPLA2-2, which lack the catalytic domain, are probably involved in the negative regulation of iPLA2 activity.,similarity:Contains 7 ANK repeats.,subunit:Forms large oligomeric 270-350 kDa structures.,tissue specificity:Four different transcripts were found to be expressed in a distinct tissue distribution.,
