Structure of the marsupial ELP and eutherian CTI genes. The ELP/CTI genes of the stripe-faced (SF) dunnart (Sminthopsis macroura) [GenBank: AC186006], fat-tailed (FT) dunnart (Sminthopsis crassicaudata) [GenBank: JN191336], koala (Phascolarctos cinereus) [GenBank: JN191337], opossum (Monodelphis domestica) [GenBank: BK008085], tammar (Macropus eugenii) [GenBank: JN191335], cat (Felis catus, Abyssinian domestic cat) [GenBank: BK008083], cow (Bos Taurus, Hereford Breed) [Ensembl: ENSBTAG00000016127], dog (Canis familiaris, Boxer breed) [GenBank: BK008082], dolphin (Tursiops truncatus) [GenBank: BK008086], pig (Sus scrofa domestica) [Ensembl: F1SD34_PIG (ENSSSCG00000007398)] and Giant panda (Ailuropoda melanoleuca) [GenBank: BK008084] have 3 exons and 2 introns. Gene size is indicated within brackets and refers to the number of nucleotides from the putative translation start (ATG, exon 1) to the polyadenylation signal (AATAAA, inclusive, exon 3). Exons are colour-coded: exon 1 (green rectangle), the Kunitz domain-encoding exon 2 (blue) and exon 3 (red) and exon size is indicated in bold text. Intron sizes are italicised. The horizontal scale bar indicates the relative sizes of the ELP/CTI genes (kb), with the putative translation start site (ATG) of all sequences aligned with the origin (0 kb). Genes are drawn approximately to scale.
