چکیده
Background: Group IIA secreted phospholipase A2 (hGIIA) is a bifunctional protein that regulates arachidonic acid metabolism by both catalysis-dependent and catalysis–independent mechanisms. Results: Selective inhibition of the catalysisindependent signaling function perturbs a hGIIA-vimentin interaction in rheumatoid synoviocytes. Conclusion: The signaling and catalytic functions of hGIIA are pharmacologically separable. Significance: Functionally selective inhibitors of hGIIA may provide new avenues for

Selective inhibition of human group IIA-secreted phospholipase A2 (hGIIA) signaling reveals arachidonic acid metabolism is associated with colocalization of hGIIA to vimentin in rheumatoid synoviocytes.
Human group IIA secreted phospholipase A2 (hGIIA) promotes tumor growth and inflammation and can act independently of its well described catalytic lipase activity via an alternative poorly understood signaling pathway. With six chemically diverse inhibitors we show that it is possible to selectively inhibit hGIIA signaling over catalysis, and x-ray crystal structures illustrate that signaling i...
متن کاملBasic residues of human group IIA phospholipase A2 are important for binding to factor Xa and prothrombinase inhibition comparison with other mammalian secreted phospholipases A2.
Human secreted group IIA phospholipase A2 (hGIIA) was reported to inhibit prothrombinase activity because of binding to factor Xa. This study further shows that hGIIA and its catalytically inactive H48Q mutant prolong the lag time of thrombin generation in human platelet-rich plasma with similar efficiency, indicating that hGIIA exerts an anticoagulant effect independently of phospholipid hydro...
متن کاملUnusual mode of binding of human group IIA secreted phospholipase A2 to anionic interfaces as studied by continuous wave and time domain electron paramagnetic resonance spectroscopy.
Human group IIA phospholipase A(2) (hGIIA) is secreted from a number of cells during inflammation and is known to interact strongly with anionic membranes and to exhibit potent Gram-positive bactericidal activity. This protein contains 23 cationic residues, which are scattered over its entire surface, resulting in a high pI of 9.39. To understand the molecular basis for the selective binding of...
متن کاملBiochemical characterization of selective inhibitors of human group IIA secreted phospholipase A(2) and hyaluronic acid-linked inhibitor conjugates.
We explored the inhibition mode of group IIA secreted phospholipase A(2) (GIIA sPLA(2)) selective inhibitors and tested their ability to inhibit GIIA sPLA(2) activity as chemical conjugates with hyaluronic acid (HA). Analogues of a benzo-fused indole sPLA(2) inhibitor were developed in which the carboxylate group on the inhibitor scaffold, which has been shown to coordinate to a Ca(2+) ligand i...
متن کاملComputational analysis of the membrane association of group IIA secreted phospholipases A2: a differential role for electrostatics.
Secreted phospholipases A2 (sPLA2's) are enzymes that hydrolyze glycerophospholipids at the sn-2 position, which leads to the production of lipid mediators of many cellular processes. These interfacial enzymes are regulated by their lipid specificity at two levels: membrane binding and substrate recognition. Different sPLA2's utilize different combinations of electrostatic and hydrophobic inter...
