Background

Nucleophosmin (NPM1), also known as B23 or numatrin, is a highly abundant, multifunctional phosphoprotein primarily localized in the granular component of the nucleolus, where it plays pivotal roles in ribosome biogenesis, centrosome duplication, and the regulation of genomic stability. As a molecular chaperone with histone-binding activity, NPM1 facilitates the assembly and transport of ribosomal subunits from the nucleolus to the cytoplasm, thereby ensuring efficient protein synthesis, while also participating in the stress response by shuttling between the nucleus and cytoplasm to regulate the stability and activity of key tumor suppressors such as p53 and ARF. Structurally characterized by its ability to form pentameric rings and undergo liquid-liquid phase separation, NPM1 is crucial for maintaining nucleolar architecture; however, its dysfunction, particularly through cytoplasmic mislocalization caused by specific mutations like NPM1c+, is a defining driver event in acute myeloid leukemia (AML), highlighting its dual significance as both an essential housekeeping protein and a critical oncoprotein when deregulated.

Immunohistochemistry

IHC shows positive staining in paraffin-embedded human testis. Anti-NPM1 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
