Background The polypyrimidine tract binding protein 1 (PTBP1), a 57 kDa RNA binding protein also known as hnRNP1, has been implicated in multiple aspect of mRNA metabolism, including regulation of alternative splicing, internal ribosome entry site-driven translation, mRNA localization, and polyadenylation. Four of tandem RNA recognition motif domains give PTBP1 a strong binding activity to RNA. Posttranscriptional regulation of gene expression by PTBP1 has been reported on many genes, including CD154, insulin, VEGF and Human inducible nitric oxide synthase.
