Gene Information

human ... SAFB(6294)

General description

Scaffold attachment factor B (SAFB) binds to RNA and DNA. It is localized to the nuclear matrix. The gene encoding SAFB is located on human chromosome 19p13.2-13.3.


Scaffold attachment factor B1 recombinant protein epitope signature tag (PrEST)

Biochem/physiol Actions

Scaffold attachment factor B (SAFB) has an important role during apoptosis. It may be involved in sorting nuclear RNA and DNA before cleavage by endonucleases. SUMOylated SAFB allows binding of RNA polymerase on the promoters of ribosomal protein genes and may also take part in RNA splicing.

Features and Benefits

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.


Corresponding Antigen APREST73765.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Although the general relevance of chromatin modifications for genotoxic stress signaling, cell-cycle checkpoint activation, and DNA repair is well established, how these modifications reach initial thresholds in order to trigger robust responses remains largely unexplored. Here, we identify the chromatin-associated...

We have found novel functions of scaffold attachment factor-B1 (SAFB) during apoptosis. The experiments showed that SAFB moved into the nucleolus 15 min after the induction of apoptosis and before the release of cytochrome c into the cytoplasm. Two hours...

We have recently discovered that the nuclear matrix protein SAFB is an oestrogen receptor corepressor. Since it has become clear that many steroid receptor cofactors play important roles in breast tumorigenesis, we investigated whether SAFB could also be involved in...
