The cytoplasmic mRNAs which are transcribed from the major late adenovirus promoter can be arranged into five 3'-coterminal families, L1 to L5. We have defined the polyadenylation sites of the mRNAs that belong to the five families at the nucleotide level. From the results, the following conclusions can be made. (i) The hexanucleotide sequence AAUAAA is present at the 3' end of all late adenovirus type 2 mRNAs and precedes the site of polyadenylation by 12 to 30 nucleotides. (ii) Between one and three A residues are present in the genomic sequence at the polyadenylation site. (iii) A sequence with the composition (T)n (A)p (T)q (n, p, q greater than or equal to 1) is found 4 to 24 nucleotides beyond all the adenovirus-specific polyadenylation sites except the 3'-coterminal family L4. This sequence is also found beyond many cellular polyadenylation sites. (iv) The L1 and L2 polyadenylation sites are very similar in structure. The other polyadenylation sites show no apparent sequence relationship, except for the hexanucleotide sequence.

D000260 Adenoviruses, Human Species of the genus MASTADENOVIRUS, causing a wide range of diseases in humans. Infections are mostly asymptomatic, but can be associated with diseases of the respiratory, ocular, and gastrointestinal systems.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
