WebIn this report we present evidence for a novel switch in the ratio of the two major iso-forms of the polypyrimidine tract binding protein (PTB) in two related prostate cancer cell lines. The existence of different isoforms of PTB is thought to be the result of alternative splicing. WebFurthermore, 3C cleaved the polypyrimidine tract-binding protein (PTB) whose interaction with the HAV IRES had been demonstrated previously. The combined results suggest that 3C-mediated cleavage of PTB might be involved in down-regulation of viral translation to give way to subsequent viral genome replication.

WebPolypyrimidine tract binding protein 2, also known as PTBP2, is a protein which in humans is encoded by the PTBP2 gene. Function. The protein encoded by this gene binds to the intronic cluster of RNA regulatory elements, downstream control sequence (DCS). It is implicated in controlling the assembly of other splicing-regulatory proteins. 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.
