PG - 529-32 AB - A murine Ets2 target gene isolated by differential display cloning was identified as the phospholipase A2 activating protein (PLAA) gene. A 2.7-kb human cDNA demonstrating high homology to mouse and rat Plaa genes was then isolated and characterized. Human PLAA contains six WD-40 repeat motifs and three different protein kinase consensus domains. Fluorescence in situ hybridization (FISH) mapping placed PLAA on chromosome 9p21, a region frequently deleted in various cancers. A comprehensive mapping strategy was employed to define further the chromosomal localization of PLAA relative to CDKN2A within the 9p21 locus. Radiation hybrid mapping placed the gene 7.69 cR from WI-5735 (LOD >3.0), a marker in close proximity to CDKN2A and CDKN2B. Yeast artificial chromosome (YAC) mapping localized PLAA proximal to the CDKN2A/CDKN2B genes and to a region flanked by D9S171 and INFA commonly deleted in many neoplasms. Two YACs contained both PLAA and D9S259, a marker present in a second more proximal minimal deleted region observed in cutaneous melanoma and squamous cell lung carcinoma. Double-color fiber FISH mapping confirmed the location of PLAA centromeric to D9S171 and CDKN2A/CDKN2B. The mapping data suggest a possible tumor suppressor role for this gene.
