Figure 1.
The TTI-encoding cDNA and its protein sequence. The complete 303-bp nucleotide sequence of TTI and the corresponding protein sequence. ATG denotes the start of the 53-aa ORF and the underlined amino acids correspond to the putative signal–peptide sequence that was not present in the peptide purified and characterized from saliva. The ∗ represents the stop codon; the bold codons aaataaa in the 3′-untranslated segment represent the putative polyadenylation signal. The poly(A)19 tail is underlined.
