General description

Poly(A)-binding protein (PABP 1) is an abundant protein that interacts with the 3′ poly(A) tail of most eukaryotic mRNAs. In vivo this protein is involved in many aspects of mRNA metabolism, including mRNA stability, translationally coupled mRNA turnover, protein biosynthesis, and ribosome biogenesis. PABP1 shuttles between the cytoplasm and the nucleus and may bind to cytoplasmic RNA sequences other than poly(A). PABP1 accumulates in the nucleus if transcription is inhibited, suggesting that nuclear export is coupled to active transcription.


This antibody recognizes PABP 1.


Epitope: Unknown

Recombinant protein corresponding to human PABP 1.
