5'-flanking region surrounding a human cytosolic phospholipase A2 gene.

The 5'-flanking region and the first four exons of a gene encoding human cytosolic phospholipase A2 (cPLA2) were isolated from a human lambda EMBL3 genomic library and sequenced. The 5'-flanking region is characterized by CA repeats, one of microsatellites. The analysis of the 5'-flanking region with transcription factor database suggests the existence of the transcription factor binding sites such as NF-kappa B, NF-IL6, AP-1, AP-2, and PEA3. These factors are well known to be induced or activated by the reagents (tumor necrosis factor alpha, interleukin-1, epidermal growth factor, and phorbol myristate acetate) reported as the inducers of a cPLA2 gene.
