Figure 6.—

Multiple sequence alignment of TRA2 proteins in L. cuprina, M. domestica, C. capitata, B. oleae, and D. melanogaster. Identical amino acids are shaded in black while similar amino acids are shaded in gray. Arrows indicate the conserved motifs that were the basis of the degenerate primers that were used to obtain Lctra2 DNA sequence. The RNA recognition motif (RRM) is underlined in red. RNP-1 and RNP-2 are the highly conserved ribonucleoprotein identifier sequences found in RRM motifs. The TRA2 proteins of all these insects are highly conserved in the RRM as well as in the flanking RS domains.
