mir-8 primary transcript (pri-mir-8) sequence, in which the the ATG codon of the miPEP-8 short open reading frame (this is present in the 5' leader of pri-mir-8) has been mutated, has been re-integrated into the attP site in the TI{TI}mir-8Δ-M insertion. This reconstitutes wild-type mir-8, but reinserts a non-translatable form of miPEP-8.
