a Co-expression of pri-miR-27a and FLAG-AGO2 constructs: wild-type (WT) and PAZ domain deletion (ΔPAZ). Detection of miR-27a-3p in input and FLAG-immunoprecipitate (IP) by Northern blot. b Nucleotide composition of miR-27a-3p oligo-tail. Horizontal axis indicates the absolute number of non-templated U nucleotides in tail, and the vertical axis indicates the cumulative percentage from the longest to the shortest oligo-tails. c, d Co-expression of pri-miR-27a and AGO2-ΔPAZ (c) or AGO2-F2L3 (d) in wild-type HEK293T or TUT4/7 DKO, and TUT4/7 DKO cells rescued with either GFP, TUT4, TUT7, or TUT4 and TUT7. Detection of miR-27a-3p by Northern blot. Source data are provided as a Source Data file.
