Vacuolar type H+-ATPase subunit A 3' untranslated region nucleotide sequence. Nucleotide sequence is depicted in the 5' to 3' direction. The diamond (♦) indicates the coding region stop (TAA). Arrows (↓) indicate sites of Poly (A) tail attachment for the four different transcripts amplified. A total of eight cDNA clones were sequenced from the 3' end, in each case the poly (A) tail was added at an adenine residue in the DNA sequence. Bold underlined motifs correspond to putative polyadenylation signals.
