Phylogenetic analysis of dsRBM proteins. The neighbor-joining tree is based on alignment of the tandem dsRBM domains. The Tribolium genome contains two R2D2-like proteins (Tc-R2D2 and Tc-C3PO) while Drosophila has only one. PACT [135], TRBP2 [136,137], and DGCR8 [138] were included as human counterparts.
