Nucleophosmin (NPM) is a ubiquitously expressed oestrogen-regulated nucleolar phosphoprotein frequently overexpressed in a variety of human malignancies. It is a multifunctional protein, modulating diverse molecular functions which include ribosome biogenesis and centrosome duplication etc. It also functions as a molecular chaperone that prevents proteins from aggregating in the crowded environment of the nucleolus. It also modulates, both positively and negatively, the activity of some tumor suppressor genes such as p53 and Arf, and it is upregulated in response to stress stimuli including DNADmageand hypoxia. It continuously shuttles between the nucleus and cytoplasm. The NPM gene which is mapped to human chromosome 5q35 is involved in several tumor-associated chromosome translocations, which have resulted in the formation of fusion proteins that retain the amino terminus of NPM, including NPM-ALK4, NPM-RAR5 and NPM-MLF1. The protein is directly involved in cancer pathogenesis, as the NPM1gene is mutated in a number of human haematopoietic malignancies, such as promyelocytic leukaemia, anaplastic large cell lymphoma, acute myeloid leukaemia, chronic myelogenous leukaemia and MDS. However its role in oncogenesis is controversial as NPM has been attributed with both oncogenic and tumor suppressive functions.
