FUSION GENES
DNA/RNA
Transcription
3629 bp mRNA; coding sequence: 1559 bp; 6 different splicings (--> 6 isoform proteins: ik1-ik6)
Proteins
Description
519 amino acids; 58 kDa; possesses 2 Zinc-finger (C2H2-type) domains: one with 4 ZnF, the second with2 ZnF; DNA binding
Expression
specificity for hematopoietic organs in the foetus and in the adult as well
Localisation
nuclear
Function
transcription regulator; can repress transcription through the recruitment of histone deacetylase complexes; role in conjunction with Aiolos; hemopoietic-specific zinc finger protein regulator of B and T-cell differentiation
Implicated in
Entity name
Note
only 2 cases to date
Hybrid gene
5 Ikaros - 3 BCL6 fusion transcript; it is supposed that substitution of the promoter of BCL6 may be responsible for BCL6 deregulation
