UniProtKB - Q13093 (PAFA_HUMAN)

Protein

Platelet-activating factor acetylhydrolase

Gene

PLA2G7

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.

Catalytic activityi

1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + H2O = 1-alkyl-sn-glycero-3-phosphocholine + acetate.

Involvement in diseasei

Platelet-activating factor acetylhydrolase deficiency (PAFAD)5 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn 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.

Asthma (ASTHMA)1 Publication
Disease susceptibility is associated with variations affecting the gene represented in this entry.
Disease descriptionThe 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 wheezing due to spasmodic contraction of the bronchi.
See also OMIM:600807
Atopic hypersensitivity (ATOPY)1 Publication
Disease susceptibility is associated with variations affecting the gene represented in this entry.
Disease descriptionA condition characterized by predisposition to develop hypersensitivity reactions. Atopic individuals can develop eczema, allergic rhinitis and allergic asthma.
