Anti-RRP1B antibody produced in rabbit

HPA017893    Human Protein Atlas characterization data

Ribosomal RNA processing 1B (RRP1B) is a 52kDa protein mainly located in the nucleolus. It possesses a nucleolar protein of 52kDa (NOP52) homology domain and an RVxF (Arg/Lys-Val/Ile-Xaa-Phe/Trp) motif. The gene encoding RRP1B is localized to human chromosome 21.

Anti-RRP1B antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige. Anti-RRP1B antibody produced in rabbit has been used for co-immunoprecipitation.

Ribosomal RNA processing 1B (RRP1B) is a metastasis modifier protein in breast cancer. It interacts with signal-induced proliferation-associated 1(SIPA1) and functions in the reduction of tumor growth. The expression of RRP1B regulates many extra cellular matrix (ECM) genes which are linked with tumor suppression. The protein has an effect on gene expression by regulating histone methylation and heterochromatinization. Along with bromodomain-containing protein 4 (Brd4), RRP1B transduces extracellular mechanistic signals to the nucleus.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
