Descripción

General description

B23 (also known as NPM, nucleophosmin, numatrin or NO38) is a phosphoprotein, widely expressed in all cell types, and localized in granular regions of the nucleolus associated with pre-ribosomal particles. This protein was found to be involved in several nuclear functions such as assembly and/or intranuclear transport of preribosomal particles, cytoplasmic/nuclear trafficking, regulation of DNA polymerase A activity and centrosome duplication. Phosphorylation of B23 is mediated by a cyclin complex, CDK2/cyclin E.
Phosphorylation causes the dissociation of B23 from the centrosome and enables the duplication of the centrosome during cell mitosis. B23 was also found to be involved in pro-myelocytic leukemia in which the gene for B23 fuses with retinoic acid receptor a (RARa). As a consequence, a fusion protein (60-7 0 kDa) is produced containing parts of the two genes.

Immunogen

rat B23 (nucleophosmin, NPM, numatrin).

Application

The antibody may be used for ELISA, competitive ELISA, immunoblotting (37 kDa), immunoprecipitation, immunocytochemistry (2% formaldehyde-acetone 1,2,5 or 10% formalin/methanol-1% NP-40 and microinjection (blocks the initiation of centrosome duplication) and immunohistochemistry. Reactivity has been observed with human, monkey, bovine, dog, hamster (weak), rat,kangaroo rat, and mouse B23.

Biochem/physiol Actions

It detects both the phosphorylated and the unphosphorylated B23 molecule. The epitope recognized by the antibody lies within the 68 amino acids at the C-terminus of B23.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% BSA and 15 mM sodium azide.

Preparation Note

Purified from culture supernatant of hybridoma cells grown in a bioreactor.
