Target Background

Alpha2 catalytic subunit of the cytosolic type I platelet-activating factor (PAF) acetylhydrolase (PAF-AH (I)) heterotetrameric enzyme that catalyzes the hydrolyze of the acetyl group at the sn-2 position of PAF and its analogs and modulates the action of PAF. The activity and substrate specificity of PAF-AH (I) are affected by its subunit composition. The alpha2/alpha2 homodimer (PAFAH1B2/PAFAH1B2 homodimer) hydrolyzes PAF and 1-O-alkyl-2-acetyl-sn-glycero-3-phosphorylethanolamine (AAGPE) more efficiently than 1-O-alkyl-2-acetyl-sn-glycero-3-phosphoric acid (AAGPA). In contrast, the alpha1/alpha2 heterodimer(PAFAH1B3/PAFAH1B3 heterodimer) hydrolyzes AAGPA more efficiently than PAF, but has little hydrolytic activity towards AAGPE. May play a role in male germ cell meiosis during the late pachytenestage and meiotic divisions as well as early spermiogenesis.
Gene References into Functions
  1. PAF is demonstrated to be the key indicator in the lipid metabolism of polypoidal choroidal vasculopathy patients in this study. PMID: 27910906
  2. PAFAH1B2 and 1B3 are important in maintaining cancer pathogenicity across a wide spectrum of cancer types. PMID: 25945974
  3. The R92H and I198T polymorphisms are highly related to the plasma PAF-AH levels and the risk of coronary heart disease, especially among patients with blood stasis syndrome. PMID: 25034894
  4. aspirin is hydrolyzed in plasma by two enzymes, BChE and a new extracellular form of platelet-activating factor acetylhydrolase, PAFAH1b2. PMID: 23508960
  5. Knockdown of PAFAH1B2 strongly reduced Abeta secretion from human cells, and this effect was confirmed in primary cells derived from PAFAH1B2 knock-out mice PMID: 23238734
  6. Plasma PAF-AH can hydrolyze oxidized phospholipids, and may attenuate the spreading of lipid peroxidation and participate in defense mechanisms against vasospasm after aneurysmal subarachnoid hemorrhage. PMID: 21866060
  7. intracellular type I PAF acetylhydrolase (PAFAH1B2 and PAFAH1B3) is the major aspirin hydrolase of human blood PMID: 21844189
  8. PAFAH1B2 is not the gene responsible for the linkage evidence on chromosome 11q23 in protein C deficiency. PMID: 17849047
  9. splice variants of the Pafah1b2 gene transcript retain exons 1-5 and replace exon 6 with alternative exons derived from genomic sequence 3' to exon 6. Splice variants encode two proteins with different novel carboxy termini PMID: 18155631
