title: Nucleotide sequence at the 5' terminus of adenovirus 2 late messenger RNA.
abstract: One major late promoter is transcriptionally active for the majority of adenovirus 2 late RNA synthesis. Nucleotide sequences proximal to this promoter are spliced onto the 5' termini of all messenger RNAs generated from it. We report here the complete nucleotide sequence of the capped 5-'terminal undecanucleotide common to these late mRNAs. The sequence m7G5'ppp5'm6AmCUCUCUUCCGp shows striking similarities to the 5'-terminal sequences of the eukaryotic alpha- and beta-globin mRNAs and contains the sequence 5'CUUCCG3' complementary to a six-base sequence near the 3' terminus of most eukaryotic 18 S ribosomal RNAs. On the basis of this sequence and the finding that this same sequence is present at the 5' end of adenovirus 2 late nuclear RNA precursor, it should now be possible to locate the major late promotor within the adenoviral genomic DNA sequence.
