    Protocol

    Specificity / Sensitivity

    Phospho-NPM1 (Thr199) Antibody detects endogenous levels of NPM1 only when phosphorylated at Thr199.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues around Thr199 of human NPM1. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Nucleophosmin (NPM; also known as B23, numatrin, or NO38) is an abundant phosphoprotein primarily found in nucleoli. It has been implicated in several distinct cellular functions, including assembly and transport of ribosomes, cytoplasmic/nuclear trafficking, regulation of DNA polymerase α activity, centrosome duplication, and molecular chaperoning activities (1,2). The NPM gene is also known for its fusion with the anaplastic lymphoma kinase (ALK) receptor tyrosine kinase. The NPM portion contributes to transformation by providing a dimerization domain, which results in activation of the fused kinase (3,4).

    NPM associates with unduplicated centrosomes and is a direct substrate of Cdk2-cyclin E in centrosome duplication (4). Upon phosphorylation at Thr199 by Cdk2-cyclin E, NPM dissociates from centrosomes, and this dissociation is a prerequisite step for centrosome to initiate duplication (5).
