WebThe Δ40p53 isoforms (also named p47 or ΔNp53) are generated by alternative splicing of intron 2 and/or alternative initiation of translation. Indeed, the retention of a part of intron 2 (i2) generates a stop codon between exons 2 and 3 in the p53i2 messenger ribonucleic acid (mRNA) that leads to the initiation of translation at AUG40.
