Nucleophosmin Antibody (NPM1)

Nucleophosmin, also known as NPM, is a protein that in humans is encoded by the NPM1 gene. The gene maps to chromosome 5q35. Nucleophosmin is likely involved in the assembly of ribosomal proteins into ribosomes. An electron microscopic study indicated that Nucleophosmin is concentrated in the granular region of the nucleolus, where ribosome assembly occurs.
