Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human NONO protein. Antibodies are purified by peptide affinity chromatography.
Background
Non-POU domain-containing octamer-binding protein (NONO), also referred to as p54nrb, is a DNA and RNA-binding protein that is involved in several nuclear processes. NONO binds to the conventional octamer duplex of double-stranded DNA, and can additionally bind to single-stranded DNA and RNA at a location independent of the duplex site (1). NONO belongs to the Drosophila melanogaster behavior, human splicing (DBHS) protein family along with paraspeckle protein 1 (PSPC1) and splicing factor, proline- and glutamine-rich (PSF/SFPQ) (2). NONO, PSPC1, and PSF/SFPQ associate together along with long nonprotein-coding RNA NEAT1 to form ribonucleic protein bodies referred to as paraspeckles, which play a role in gene expression and regulation (2). NONO heterodimerizes with PSF/SFPQ to process pri-miRNA prior to presentation to the Drosha complex (3). The NONO/PSF heterodimer can also stabilize paired DNA ends and promote DNA double-strand break repair by canonical non-homologous end rejoining (4). NONO also forms a complex with PSF/SFPQ and DExH-box helicase 9 (DHX9) that produces a long isoform of BIN1, promoting carcinogenesis in hepatocellular carcinoma (5). In breast cancer, NONO regulates pre-mRNA splicing and binding to mRNAs of cell proliferation-related genes, regardless of hormone sensitivity (6). NONO has also been hypothesized to play a role in heart disease, and a recent study in mice showed that NONO deficiency led to heart defects by fibroblast hyperproliferation (7).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
