Xenopus U3 snoRNA GAC-Box A′ and Box A Sequences Play Distinct Functional Roles in rRNA Processing
Mutations in the 5′ portion of Xenopus U3 snoRNA were tested for function in oocytes. The results revealed a new cleavage site (A0) in the 3′ region of vertebrate external transcribed spacer sequences. In addition, U3 mutagenesis uncoupled cleavage at sites 1 and 2, flanking the 5′ and 3′ ends of 18...
