Rabbit anti Human polyadenylate-binding protein 1 antibody recognizes polyadenylate-binding protein 1, also known as poly(A) binding protein, cytoplasmic 2.

Encoded by the PABPC1 gene, polyadenylate-binding protein 1 is a poly(A) binding protein. This protein shuttles between the nucleus and cytoplasm and binds to the 3' poly(A) tail of eukaryotic messenger RNAs via RNA-recognition motifs. The binding of this protein to poly(A) promotes ribosome recruitment and translation initiation; it is also required for poly(A) shortening which is the first step in mRNA decay. The gene is part of a small gene family including three protein-coding genes and several pseudogenes (provided by RefSeq, Aug 2010).

Rabbit anti Human polyadenylate-binding protein 1 antibody detects a band of 71 kDa. The antibody has been extensively validated for western blotting using whole cell lysates.
