Aligned predicted amino sequences for vertebrate lengsins (with accession numbers); Zebrafish (zfish) [AAZ29482], Chicken [ABC40398], Mouse [AAN38298], Rat [AAP34385], Guinea pig (Gpig) [ABC59314], Rabbit [DQ885946], Dog [ABD74632], Human [AAF61255]. Sequences are colored to illustrate exon structure for each gene taken from publicly available genome sequences (for rabbit and guinea pig these are inferred from other species).
