Molecular characterization of cDNA for phospholipase A2-activating protein
Abstract
A phospholipase A2-activating protein (PLAP) cDNA was cloned and sequenced from a human monocyte cDNA library, and expressed as a histidine-tagged fusion protein. The DNA-deduced aa sequence of human PLAP was 80,826 Da; however, SDS-PAGE analysis revealed a 72-74 kDa protein which matched the size of native PLAP from human monocytes. Anti-sense plap oligonucleotide blocked cholera toxin-induced release of 3H-labeled arachidonic acid from cells, indicating a potential role for PLAP in regulating phospholipase A2 activity.
