From: The gene structure and hypervariability of the complete Penaeus monodon Dscam gene

Multiple amino acid sequence alignments of each of the PmDscam extracellular variable regions. (A) 26 variants encode the N-terminal Ig2 domain in the Ig2 exon 4 cluster. (B) 81 variants encode the N-terminal Ig3 domain in the Ig3 exon 6 cluster. (C) 26 variants encode the entire Ig7 domain in the Ig7 exon 15 cluster. The total number of amino acids for each isoform is indicated on the right. Identical (black) and similar (grey and light grey) amino acids are indicated. Exon#: the exon numbers correspond to the exon’s location in the PmDscam gene.
