" /> polypyrimidine Tract-Binding protein - CISMeF





Preferred Label : polypyrimidine Tract-Binding protein;

MeSH definition : A RNA-binding protein that binds to polypyriminidine rich regions in the INTRONS of messenger RNAs. Polypyrimidine tract-binding protein may be involved in regulating the ALTERNATIVE SPLICING of mRNAs since its presence on an intronic RNA region that is upstream of an EXON inhibits the splicing of the exon into the final mRNA product.;

MeSH synonym : pptb; ptb splicing factor; p57 cytoplasmic rna-binding protein; tract-binding protein, polypyrimidine; splicing factor, ptb; ptb protein; p57 cytoplasmic rna binding protein; polypyrimidine tract binding protein;

Registry Number MeSH : 139076-35-0;

Is substance : O;
