Rabbit Anti-PAFAH/FITC Conjugated antibody
background:
This gene encodes platelet-activating factor acetylhydrolase isoform 2, a single-subunit intracellular enzyme that catalyzes the removal of the acetyl group at the SN-2 position of platelet-activating factor (identified as 1-O-alkyl-2-acetyl -sn-glyceryl-3-phosphorylcholine). However, this lipase exhibits a broader substrate specificity than simply platelet activating factor. Two other isoforms of intracellular platelet-activating factor acetylhydrolase exist, and both are multi-subunit enzymes. Additionally, there is a single-subunit serum isoform of this enzyme.
Function:
Modulates the action of platelet-activating factor (PAF) by hydrolyzing the sn-2 ester bond to yield the biologically inactive lyso-PAF. Has a specificity for substrates with a short residue at the sn-2 position. It is inactive against long-chain phospholipids.
Subcellular Location:
Secreted, extracellular space.
Tissue Specificity:
Plasma.
DISEASE:
Platelet-activating factor acetylhydrolase deficiency (PAFAD) [MIM:614278]: An enzymatic deficiency that results in exacerbated bodily response to inflammatory agents. It can be associated with several disease states including inflammatory gastrointestinal disorders, asthma and atopy. Asthmatic individuals with PAFAD may manifest aggravated respiratory symptoms. Note=The disease is caused by mutations affecting the gene represented in this entry.
Asthma (ASTHMA) [MIM:600807]: The most common chronic disease affecting children and young adults. It is a complex genetic disorder with a heterogeneous phenotype, largely attributed to the interactions among many genes and between these genes and the environment. It is characterized by recurrent attacks of paroxysmal dyspnea, with weezing due to spasmodic contraction of the bronchi. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Atopic hypersensitivity (ATOPY) [MIM:147050]: A condition characterized by predisposition to develop hypersensitivity reactions. Atopic individuals can develop eczema, allergic rhinitis and allergic asthma. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Similarity:
Belongs to the AB hydrolase superfamily. Lipase family.

脂蛋白相关磷脂A2(Lp-PLA2)也称血浆血小板激活因子乙酰水解酶,是介导氧化低密度脂蛋白引起炎症和动脉粥样硬化的一个关键性酶。
脂蛋白相关磷脂酶A2是磷脂酶A2超家族的一个成员,由成熟的巨噬细胞和淋巴细胞合成和分泌,主要与低密度脂蛋白结合,能水解低密度脂蛋白上的氧化卵磷脂,生成促炎物质溶血卵磷脂和氧化型游离脂肪酸,促进动脉粥样硬化形成,经研究认为:抑制脂蛋白相关磷脂酶A2活性可能有抗动脉粥样硬化的效应。
