Nucleophosmin (NPM1)

Target
NPM1
Molecular classification
RNA Binding Protein, Histone Chaperone, Phosphoprotein
01

Overview

Nucleophosmin/NPM1 is an essential multifunctional protein involved primarily in ribosome biogenesis/histone chaperoning/genomic stability/cell cycle control/apoptosis regulation. It achieves these functions through dynamic subcellular localization regulated by post-translational modifications. Its dysregulation—by mutation or overexpression—is strongly implicated especially in hematologic malignancies like AML but also many solid cancers.
