Polypyrimidine tract-binding protein ptb

WebMar 27, 2024 · Polypyrimidine tract binding protein (PTB) is a major hnRNP protein with multiple roles in mRNA metabolism, including regulation of alternative splicing and internal ribosome entry site-driven translation. WebApr 14, 1998 · Polypyrimidine tract-binding protein (PTB), also known as hnRNP I, is a member of the hnRNP family [2-4]. PTB has been proposed as a splicing factor, since PTB was identified as a protein binding to the polypyrimidine tracts (Py-tracts) typically found near the 3′ end of introns [3, 4].
