2.7.7.52 | additional information | isoform RET1 adds U tails to gRNAs, rRNAs, and selected mRNAs and contributes U residues into A/U heteropolymers. Isoform RET1's terminal uridylyl transferase activity is required for the nucleolytic processing of gRNA, rRNA, and mRNA precursors. The U tails presence does not affect the stability of gRNAs and rRNAs, while transcript-specific uridylylation triggers 3' to 5' mRNA decay. The minicircle-encoded antisense transcripts, which are stabilized by RET1-catalyzed uridylylation, may direct a nucleolytic cleavage of multicistronic precursors | Trypanosoma brucei | ? | - |
