Rabbit monoclonal antibody [EP1848Y] to NPM (N-term)Nucleophosmin (NPM), a nucleocytoplasmic shuttling protein with prominent nucleolar localization, regulates the ARF-p53 tumor-suppressor pathway. Translocations involving the NPM gene cause cytoplasmic dislocation of the NPM protein . NPM is a major nucleolar protein which is 20 times more abundant in tumor or proliferating cells than in normal resting cells. Data suggest that transcription factor YY1 may play a role in NPM gene expression . A chromosomal translocation associated with myelodysplastic syndrome and acute myeloid leukemia (AML) was found to rearrange part of the nucleophosmin (NPM) gene. Myeloid leukemia factor 1 (MLF1) binds NPM and studies have indicated that MLF1 is normally located in the cytoplasm, whereas NPM-MLF1 is targeted to the nucleus, with highest levels in the nucleolus. The nuclear/nucleolar localization of NPM-MLF1 mirrors that of NPM, indicating that NPM trafficking signals direct MLF1 to an inappropriate cellular compartment in myeloid leukemia cells
Immunogen
A synthetic peptide corresponding to residues on the N-terminus of human NPM was used as an immunogen.
