Myosin genes of Drosophila melanogaster and Daphnia pulex. (A) The myosin heavy chain (MHC) gene of D. melanogaster (FlyBase annotation ID:CG17927) showing the common and alternatively spliced exons (LCB, light chain-binding domain) [31,32,58] (B) Putative architecture of the muscle MHC gene of D. pulex (scaffold_6: 2047569–2071828). ATG and TAA indicate the start of translation and the stop codon, respectively. In the Drosophila MHC transcripts, the sequence of the terminal exon can be replaced by that of the 'differentially included exon'.
