Schematic diagram of the gene structure of three isoforms of LYP. Exons are represented by bars and drawn approximately proportional to their sizes and positions. The open part of bars stands for non-translational regions. The numbers of exons are selectively labeled based on the LYP1 coding sequence. Note that LYP3 has a short exon 15 and LYP2 contains a longer exon 16 with an in-frame stop codon. All the intron-exon junctions follow the GT-AG rule.
