Encyclopedia
Polypyrimidine tract-binding protein is an RNA-binding protein
, also known as PTB or hnRNP I. PTB functions mainly as a splicing regulator, although it is also involved in alternative 3' end processing, mRNA stability and RNA localization.
RNA-binding protein
RNA-binding proteins are proteins that bind to RNA. They bind to either double-strand or single-strand RNAs through RNA recognition motif . RNA-binding proteins may regulate the translation of RNA, and post-transcriptional events, such as RNA splicing, editing.They are cytoplasmic and nuclear...
