General description

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.

Immunogen

Recombinant protein corresponding to bovine PABP-2.

Physical form

Rabbit polyclonal in buffer containing serum with 0.05% sodium azide.

Unpurified

Quality

Evaluated by Western Blotting in A431 cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected PABP-2 in 10 µg of A431 cell lysate.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Target description

~ 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).
