The 3’UTRs from mbpa and mbpb affect the cellular localization of mRNA. WISH on transgenic larvae with probes specific for Dendra2 (A,D,G), mbpa (B,E,H), or mbpb mRNA (C,F,I), as indicated. All pictures represent dorsal views of the neck region. mRNAs localized in cell bodies are indicated by black arrows, and localization in myelin sheaths is marked by white arrows. In the Tg(mbpa:Dendra2) larvae, Dendra2 mRNA is exclusively localized in cell bodies (A). This localization is markedly different from the localization of Dendra2 mRNA when the 3’UTR from either mbpa or mbpb is present (D,G). The localization of endogenous mbpa (B,E,H) and mbpb (C,F,I) mRNAs is similar in all three transgenic strains. (J) Enlarged view of the neck region of Dendra2 WISH of (A,D,G).
