Target

  • FunctionInvolved in diverse cellular processes such as ribosome biogenesis, centrosome duplication, protein chaperoning, histone assembly, cell proliferation, and regulation of tumor suppressors p53/TP53 and ARF. Binds ribosome presumably to drive ribosome nuclear export. Associated with nucleolar ribonucleoprotein structures and bind single-stranded nucleic acids. Acts as a chaperonin for the core histones H3, H2B and H4. Stimulates APEX1 endonuclease activity on apurinic/apyrimidinic (AP) double-stranded DNA but inhibits APEX1 endonuclease activity on AP single-stranded RNA. May exert a control of APEX1 endonuclease activity within nucleoli devoted to repair AP on rDNA and the removal of oxidized rRNA molecules. In concert with BRCA2, regulates centrosome duplication. Regulates centriole duplication: phosphorylation by PLK2 is able to trigger centriole replication. Negatively regulates the activation of EIF2AK2/PKR and suppresses apoptosis through inhibition of EIF2AK2/PKR autophosphorylation.
  • Involvement in diseaseA chromosomal aberration involving NPM1 is found in a form of non-Hodgkin lymphoma. Translocation t(2;5)(p23;q35) with ALK. The resulting chimeric NPM1-ALK protein homodimerize and the kinase becomes constitutively activated.
    A chromosomal aberration involving NPM1 is found in a form of acute promyelocytic leukemia. Translocation t(5;17)(q32;q11) with RARA.
    A chromosomal aberration involving NPM1 is a cause of myelodysplastic syndrome (MDS). Translocation t(3;5)(q25.1;q34) with MLF1.
    Defects in NPM1 are associated with acute myelogenous leukemia (AML). Mutations in exon 12 affecting the C-terminus of the protein are associated with an aberrant cytoplasmic location.
  • Sequence similaritiesBelongs to the nucleoplasmin family.
  • Post-translational
    modifications
    Acetylated at C-terminal lysine residues, thereby increasing affinity to histones.
    ADP-ribosylated.
    Phosphorylated at Ser-4 by PLK1 and PLK2. Phosphorylation at Ser-4 by PLK2 in S phase is required for centriole duplication and is sufficient to trigger centriole replication. Phosphorylation at Ser-4 by PLK1 takes place during mitosis. Phosphorylated by CDK2 at Ser-125 and Thr-199. Phosphorylation at Thr-199 may trigger initiation of centrosome duplication. Phosphorylated by CDK1 at Thr-199, Thr-219, Thr-234 and Thr-237 during cell mitosis. When these four sites are phosphorated, RNA-binding activity seem to be abolished. May be phosphorylated at Ser-70 by NEK2. The Thr-199 phosphorylated form has higher affinity for ROCK2. CDK6 triggers Thr-199 phosphorylation when complexed to Kaposi's sarcoma herpesvirus (KSHV) V-cyclin, leading to viral reactivation by reducing viral LANA levels.
    Sumoylated by ARF.
  • Cellular localizationNucleus > nucleolus. Nucleus > nucleoplasm. Cytoplasm > cytoskeleton > microtubule organizing center > centrosome. Generally nucleolar, but is translocated to the nucleoplasm in case of serum starvation or treatment with anticancer drugs. Has been found in the cytoplasm in patients with primary acute myelogenous leukemia (AML), but not with secondary AML. Can shuttle between cytoplasm and nucleus. Co- localizes with the methylated form of RPS10 in the granular component (GC) region of the nucleolus. Colocalized with nucleolin and APEX1 in nucleoli. Isoform 1 of NEK2 is required for its localization to the centrosome during mitosis.

  • ab10530 at 1/250 staining human colon cancer tissue sections by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was then blocked with serum and incubated with the antibody for 30 minutes at 22°C. An HRP conjugated goat anti-mouse antibody was used as the secondary.

  • Predicted band size : 33 kDa
    Observed band size : 38 kDa (why is the actual band size different from the predicted?)

  • ab10530 staining Nucleophosmin in immortalized Human trabecular meshwork cells by Immunocytochemistry/ Immunoflourescence. Cells were PFA-fixed and permeabilized in 0.5% Triton X-100 prior to blocking in 3% BSA for 45 minutes at room temperature. The primary antibody was diluted 1/1000 in PBS/0.3% BSA and incubated with the sample for 2 hours. The secondary antibody was Cy3®-conjugated Donkey anti-Mouse polyclonal, diluted 1/1000.

Thank you for contacting us.

The epitope of ab10530 lies within 68 amino acid at the C-terminus of B23 isoform 1. As the sequence of human nucleophosmin isoform 3 replaces the amino acid of a.a 258-294 of isoform 1 with amino acid AH, it is un...

Thank you for your reply.

I can confirm that ab4098 and ab10530 are different clone numbers ([NA24] and [FC82291]) and so they are different antibodies raised against different immunogens and detecting different epitopes within the Nucleopho...
