Cloning and recombinant expression of human group IIF-secreted phospholipase A(2).
Valentin E., Singer A.G., Ghomashchi F., Lazdunski M., Gelb M.H., Lambeau G.
Mammalian-secreted phospholipases A(2) (sPLA(2)) form a diverse family of at least nine enzymes that hydrolyze phospholipids to release free fatty acids and lysophospholipids. We report here the cloning and characterization of human group IIF sPLA(2) (hGIIF sPLA(2)). The full-length cDNA codes for ... >> More
Mammalian-secreted phospholipases A(2) (sPLA(2)) form a diverse family of at least nine enzymes that hydrolyze phospholipids to release free fatty acids and lysophospholipids. We report here the cloning and characterization of human group IIF sPLA(2) (hGIIF sPLA(2)). The full-length cDNA codes for a signal peptide of 20 amino acid followed by a mature protein of 148 amino acids containing all of the structural features of catalytically active group II sPLA(2)s. hGIIF sPLA(2) gene is located on chromosome 1 and lies within a sPLA(2) gene cluster of about 300 kbp that also contains the genes for group IIA, IIC, IID, IIE, and V sPLA(2)s. In adult tissues, hGIIF is highly expressed in placenta, testis, thymus, liver, and kidney. Finally, recombinant expression of hGIIF sPLA(2) in Escherichia coli shows that the enzyme is Ca(2+)-dependent, maximally active at pH 7-8, and hydrolyzes phosphatidylglycerol versus phosphatidylcholine with a 15-fold preference. << Less

Immunomodulatory lysophosphatidylserines are regulated by ABHD16A and ABHD12 interplay.
Kamat S.S., Camara K., Parsons W.H., Chen D.H., Dix M.M., Bird T.D., Howell A.R., Cravatt B.F.
Lysophosphatidylserines (lyso-PSs) are a class of signaling lipids that regulate immunological and neurological processes. The metabolism of lyso-PSs remains poorly understood in vivo. Recently, we determined that ABHD12 is a major brain lyso-PS lipase, implicating lyso-PSs in the neurological dis ... >> More
Lysophosphatidylserines (lyso-PSs) are a class of signaling lipids that regulate immunological and neurological processes. The metabolism of lyso-PSs remains poorly understood in vivo. Recently, we determined that ABHD12 is a major brain lyso-PS lipase, implicating lyso-PSs in the neurological disease polyneuropathy, hearing loss, ataxia, retinitis pigmentosa and cataract (PHARC), which is caused by null mutations in the ABHD12 gene. Here, we couple activity-based profiling with pharmacological and genetic methods to annotate the poorly characterized enzyme ABHD16A as a phosphatidylserine (PS) lipase that generates lyso-PS in mammalian systems. We describe a small-molecule inhibitor of ABHD16A that depletes lyso-PSs from cells, including lymphoblasts derived from subjects with PHARC. In mouse macrophages, disruption of ABHD12 and ABHD16A respectively increases and decreases both lyso-PSs and lipopolysaccharide-induced cytokine production. Finally, Abhd16a(-/-) mice have decreased brain lyso-PSs, which runs counter to the elevation in lyso-PS in Abhd12(-/-) mice. Our findings illuminate an ABHD16A-ABHD12 axis that dynamically regulates lyso-PS metabolism in vivo, designating these enzymes as potential targets for treating neuroimmunological disorders. << Less
