Western Blot (WB)

(NPM1 Antibody (N-term) western blot analysis in Hela cell line lysates (35ug/lane).This demonstrates the NPM1 antibody detected the NPM1 protein (arrow).)

Immunofluorescence (IF)

(Fluorescent image of A549 cell stained with NPM1 Antibody (N-term).A549 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with NPM1 primary antibody (1:25, 1 h at 37 degree C). For secondary antibody, Alexa Fluor 488 conjugated donkey anti-rabbit antibody (green) was used (1:400, 50 min at 37 degree C).Cytoplasmic actin was counterstained with Alexa Fluor 555 (red) conjugated Phalloidin (7units/ml, 1 h at 37 degree C).NPM1 immunoreactivity is localized to Nucleus and Nucleolus significantly.)

Immunohistochemistry (IHC)

(Formalin-fixed and paraffin-embedded human lymph tissue reacted with NPM1 antibody (N-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.)

Flow Cytometry (FC/FACS)

(NPM1 Antibody (N-term) flow cytometric analysis of Hela cells (right histogram) compared to a negative control cell (left histogram).FITC-conjugated donkey-anti-rabbit secondary antibodies were used for the analysis.)

NCBI Description

The protein encoded by this gene is involved in several cellular processes, including centrosome duplication, protein chaperoning, and cell proliferation. The encoded phosphoprotein shuttles between the nucleolus, nucleus, and cytoplasm, chaperoning ribosomal proteins and core histones from the nucleus to the cytoplasm. This protein is also known to sequester the tumor suppressor ARF in the nucleolus, protecting it from degradation until it is needed. Mutations in this gene are associated with acute myeloid leukemia. Dozens of pseudogenes of this gene have been identified. [provided by RefSeq, Aug 2017]

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.

Chromosomal Location of Human Ortholog: 5q35.1

Cellular Component: nucleoplasm; centrosome; focal adhesion; membrane; cytoplasm; nucleolus; spindle pole centrosome; cytosol; ribonucleoprotein complex; nucleus

Molecular Function: protein homodimerization activity; protein kinase inhibitor activity; histone binding; RNA binding; transcription coactivator activity; unfolded protein binding; protein kinase binding; ribosomal large subunit binding; NF-kappaB binding; protein binding; protein heterodimerization activity; Tat protein binding; ribosomal small subunit binding
