Fig. 2.
Nucleotide sequence of the P5′N-1 gene.
The exonic sequence is shown in uppercase letters, and the intronic sequence is shown in lowercase letters. Predicted amino acid sequence is shown below the nucleotide sequence. The final codon of exon 1 acts as the initiator codon for the 286–amino acid form of P5′N-1, whereas the translation is initiated by the first codon of exon 2 in the longer 297–amino acid form of the protein.
