title: Genomic organization of the murine CTL lipase gene.
abstract: Murine cytotoxic T-lymphocyte (CTL) lipase was originally identified as an IL-4-inducible gene in CD8-positive T cells. To further our understanding of both the function and the regulation of CTL lipase in T cells, we have cloned and characterized the murine gene. Two overlapping phage clones spanning 29 kb contain the entire CTL lipase gene. The exon structure is similar to those characterized for the human and canine pancreatic lipase-related protein 1 genes, with notable differences in the 5' end. Transcripts initiate from a site that matches a consensus for an initiator sequence. Potential cis-regulatory elements in the CTL lipase 5' regulatory region that would confer dual tissue specificity in exocrine pancreas and cytotoxic T lymphocytes are identified. The implications of this promoter organization are discussed.
