Transcription in a centromeric --> telomeric orientation; transcription is cell-cycle regulated, reaching peaks at G1/S transition and being baseline at S/G2 1.6 kb mRNA

Protein

 
  DNA Diagram
Description 294 amino acids, 32.5 kDa; contains in C-term an oligomerization domain (residues 1-83), a metal binding site (residues 104-115) , 2 domains rich in acidic amino acids (residues 120- 132 and 161-188) , and 2 nuclear localisation signals in C-term; forms homo-hexameres; binds to single and double strand nucleic acids
Expression wide
Localisation nuclear, mainly in the nucleolus
Function RNA binding nucleolar phosphoprotein involved in preribosomal assembly; transport ribonucleoproteins between cellular compartments
Homology with nucleoplasmin

Implicated in

Entity Anaplasic large cell lymphoma (ALCL) with t(2;5)(p23;q35) --> NPM1-ALK
Disease ALCL are high grade non Hodgkin lymphomas; ALK+ ALCL are ALCL where ALK is involved in a fusion gene; ALK+ ALCL represent 50 to 60 % of ALCL cases (they are CD30+, ALK+;); 80% of ALK+ ALCL cases bear a t(2;5)
Prognosis nonetheless, a 80% five yr survival may be associated with this anomaly
Cytogenetics additional anomalies are most often found
Hybrid/Mutated Gene 5' NPM1-3' ALK on der(5)
Abnormal Protein 680 amino acids, 80 kDa; N-term 116 amino acids from NPM1 fused to the 563 C-term aminoacids of ALK (i.e. composed of the oligomerization domain and the metal binding site of NPM1 ,and the entire cytoplasmic portion of ALK); no apparent expression of the ALK/NPM1 counterpart; Characteristic localisation both in the cytoplasm and in the nucleus, due to heterooligomerization of NPM-ALK and normal NPM whereas the normal NPM protein is confined to the nucleus; constitutive activation of the catalytic domain of ALK.
Oncogenesis via the kinase function activated by oligomerization of NPM1-ALK mediated by the NPM1 part
  
Entity t(3;5)(q25;q34)/in myeloid malignancies --> NPM - MLF1
Disease Acute non lymphocytic leukemia (ANLL), myelodysplasia (MDS), chronic myelogenous leukemia in blast crisis (BC-CML); trilineage involvement
Prognosis very poor
Cytogenetics location of breakpoints difficult to ascertain
Hybrid/Mutated Gene 5' NPM-3' MLF1 on der(5)
Abnormal Protein with the 175 N term amino acids of NPM1; nuclear protein
  
Entity t(5;17)(q34;q21)/M3-ANLL --> NPM1-RARa
Disease promyelocytic ANLL (M3-ANLL)
Cytogenetics variant translocation of the well known t(15;17)
Hybrid/Mutated Gene 5' NPM1-3' RARa on der(5)
Abnormal Protein with the 117 N term amino acids of NPM1
  

Breakpoints

 
 
Note within the 4th intron in the cases of t(2;5) or t(5;17), within the 6th intron in case of t(3;5)
