Synonyms

PTB Protein

PTB Splicing Factor

Polypyrimidine Tract Binding Protein

Splicing Factor, PTB

Tract-Binding Protein, Polypyrimidine

p57 Cytoplasmic RNA Binding Protein

p57 Cytoplasmic RNA-Binding Protein

pPTB

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.
