Anti-PABP-2 Antibody

PABPN1, also known as Polyadenylate-binding protein 2, Poly(A)-binding protein II (PABP-2), Poly(A)-binding protein 2, PABII, Nuclear poly(A)-binding protein 1,or Polyadenylate-binding nuclear protein 1, and encoded by the gene PABPN1/PAB2/PABP2, is a RNA binding protein involved in the 3′-end formation of mRNA precursors (pre-mRNA) by the addition of a poly(A) tails. PABPN1 stimulates poly(A) polymerase (PAPOLA) tail elongation and controls the poly(A) tail length. PABPN1is also important in nucleocytoplasmic trafficking and nonsense-mediated decay (NMD) of mRNA and appears to also protect the poly(A) tail from degradation. PABPN1 is localized to the nucleus and cytoplasm. PABPN1 is found in cytoplasmic mRNP granules containing untranslated mRNAs and shuttles between the nucleus and the cytoplasm but is predominantly found in the nucleus.

~ 50 kDa observed. The calculated molecular weight is 34 kDa, however PABP-2 has been shown as a ~50 kDa band in western blots (Nemeth A. K, et al. (1995). Nucleic Acids Res. 23(20):4034-41).

Recombinant protein corresponding to bovine PABP-2.

Immunoprecipitation Analysis: A representative lot immunoprecipitated PABP-2 in mouse limb tissue lysate.
Immunocytochemistry Analysis: A representative lot detected PABP-2 in mouse limb cells.
