WebMfold. The IRES activity was found to be influenced by the interaction of trans-acting factor, polypyrimidine tract binding protein (PTB). Deletion of 25 nts from the 39terminus of the 59untranslated region resulted in reduced binding with PTB protein and also showed significant decrease in IRES activity compared to the wild type.
