Fig. 4

Sequence analysis of the two BdPyx splice forms. a Two molecular isoforms of BdPyx mRNAs detected via PCR. b Cartoon illustration of the two transcripts from BdPyx. The shorter of these transcripts includes a truncated exon 6 that originates from the use of an alternative spliced donor site, marked with a black box alongside nucleotide sequences. c Comparison of amino acid sequences deduced for BdPyx-L, BdPyx-S, and DmPyx. The labels in this figure are the same as in Fig. 2. Ankyrins are denoted AR1 to AR9. The red box denotes amino acid residues originating from alternative splicing of the BdPyx gene
