NPM1, also known as nucleolar phosphoprotein B23 or numatrin, has Chromosomal aberrations found in patients with non-Hodgkin lymphoma, acute promyelocytic leukemia, myelodysplastic syndrome, and acute myelogenous leukemia, and Heterozygous mice for NPM1 are vulnerable to tumor development.
Nucleophosmin (NPM), also known as nucleolar phosphoprotein B23 or numatrin, is a protein that in humans is encoded by the NPM1 gene. Chromosomal aberrations involving NPM1 were found in patients with non-Hodgkin lymphoma, acute promyelocytic leukemia, myelodysplastic syndrome, and acute myelogenous leukemia. Heterozygous mice for NPM1 are vulnerable to tumor development.
