Plasminogen activator inhibitor 2 (PAI-2) plays an essential role in the regulation of localized extracellular proteolysis by its inactivation of urokinase. Using probes derived from a cDNA we isolated from lipopolysaccharide (LPS)-stimulated human peripheral blood monocytes, we have mapped, isolated, and determined the molecular organization of the gene for PAI-2 (PLANH2). In situ hybridization of the cDNA to normal metaphase chromosomes has confirmed our prior assignment of the gene for PAI-2 to chromosome 18 and further localized it to the long arm at 18q21.2-18q22. We have isolated nine independent genomic clones, two of which were found to contain the entire PAI-2 transcriptional unit of approximately 16.4 kilobase pairs (kbp). Analysis of the gene organization by restriction enzyme mapping, Southern blotting, and DNA sequencing revealed that the cDNA sequence is divided among eight exons interrupted by seven introns, the junctions of which all conform to the "GT-AG" consensus rule. In common with the arrangement found throughout, the serpin superfamily, of which PAI-2 is a member, the first intron is located just 5' to the initiator methionine residue, and the 3' untranslated region (UTR) is not interrupted by a splice junction. Determination of the transcription initiation site by primer extension analysis of monocytic mRNA indicated that our PAI-2 cDNA was, at most, only three nucleotides short of full length, yielding a primary PAI-2 transcript with a 66-bp first exon. A promoter "TATAAAbox" is located 30 bp upstream of the "cap" site.(ABSTRACT TRUNCATED AT 250 WORDS)
