(A) Alternative splicing present in lysophospholipase gene transcripts as long (L, accession no. AF077198) and short (S, accession no. AF077199) forms. The numbers indicate the amino acid positions of deduced proteins. Note that the ORF is maintained in the alternatively spliced S isoform. (B) Overlapping of HSPC070 (accession no.AF161555) and RAF genes located on opposite DNA strands at the same locus. Both genes are mapped to the same region on chromosome 3p25. The comparison of sequences between cDNAs and genomic DNA has allowed the exon–intron structure of both genes to be established, with exons represented by boxes and their numbers indicated. Note that a stretch of 105 bp is shared by the 3′ UTRs of both genes. Arrows indicate the orientations of transcription.
