Background: Nucleophosmin 1 (NPM1), also known as nucleolar phosphoprotein B23 or numatrin, is a member of the nucleoplasmin family. Nucleophosmin (NPM) is a nucleolar phosphoprotein that plays multiple roles in ribosome assembly and transport, cytoplasmic-nuclear trafficking, centrosome duplication, and regulation of p53. The NPM1 gene is frequently involved in chromosomal translocation, mutation, and deletion. Mutations of the NPM1 gene leading to the expression of a cytoplasmic mutant protein, NPMc+, are the most frequent genetic abnormalities found in acute myeloid leukemias. Acute myeloid leukemia (AML) with mutated NPM1 have distinct characteristics, including a significant association with a normal karyotype, the involvement of different hematopoietic lineages, a specific gene-expression profile, and clinically, a better response to induction therapy, and a favorable prognosis. Also, NPM1 is a crucial gene to consider in the context of the genetics and biology of cancer. NPM1 is frequently overexpressed, mutated, rearranged, and deleted in human cancer. Traditionally regarded as a tumor marker and a putative proto-oncogene, it has now also been attributed with tumor-suppressor functions.

NCBI Description

This gene encodes a phosphoprotein which moves between the nucleus and the cytoplasm. The gene product is thought to be involved in several processes including regulation of the ARF/p53 pathway. A number of genes are fusion partners have been characterized, in particular the anaplastic lymphoma kinase gene on chromosome 2. Mutations in this gene are associated with acute myeloid leukemia. More than a dozen pseudogenes of this gene have been identified. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Nov 2009]

Uniprot Description

NPM1: a nucleolar protein associated with nucleolar ribonucleoprotein structures and that binds single-stranded nucleic acids. Is a major component of template activating factor (TAF)-III. It plays a role in controlling centrosome duplication, and may function in the assembly and/or transport of the ribosome. Two alternatively spliced isoforms have been described.
