MblC-specific sequences are found in distantly related invertebrates.

Numbers indicate percentage of identity (best local alignment) between dynamically translated genomic DNA and isoform-specific Muscleblind protein sequences, except for species marked with an asterisk (*) for which only Expressed Sequence Tag (EST) sequences were available in databases. Accession numbers of ESTs containing isoform-specific sequences are: aBM605179, bBM619051.1, cCV835929.1, dyk381a7.5, eBQ094923.1. Non-significant similarity is indicated by a minus sign (-) and data not available, at the time of the analysis, by an empty cell. Species are listed by phylogenetic distance to Drosophila melanogaster[65]. Multiple alignments are shown in Figure S1.
