Identification of marsupial orthologue of SLC22A2 in the tammar. A Exon structure of mouse Slc22a2, human SLC22A2 and tammar putative SLC22A2. Black boxes and white boxes represent protein-coding exon and UTRs, respectively. B 5ʹ and 3ʹ RACE primers and RACE results. Full-length of tammar SLC22A2 encoding 554 a.a. was determined by RACE experiments. Asterisks indicate RACE product containing partial SLC22A2 sequences. 3ʹ RACE product contained poly-A signal (red-letters) and poly-A tail (green letters). C Protein alignment. Red-coloured highlight represents the major facilitator superfamily (MFS) domain of the tammar SLC22A2
