Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

NCBP1/CBP80 recognizes endogenous levels of total NCBP1/CBP80 protein.


Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val452 of human NCBP1/CBP80 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Nuclear cap-binding protein subunit 1 (NCBP1), also known as cap-binding protein 80 (CBP80), plays a role in nuclear pre-mRNA splicing (1,2). It has also been shown to function in the nonsense-mediated decay (NMD) of mRNAs where translation is prematurely terminated (3). NCBP1/CBP80 increases the efficiency of NMD by promoting the interaction of two active NMD components Upf1 and Upf2 (4).
