Genes Involved and Proteins
Note
The partner of EVI1 is yet unknown.
Gene name

Location
3q26.2
Protein description
Transcrition factor; EVI1 targets include:GATA2, ZBTB16 /PLZF, ZFPM2/FOG2, JNK and the PI3K/AKT pathway. Role in cell cycle progression, likely to be cell-type dependant; antiapoptotic factor; involved in neuronal development organogenesis; role in hematopoietic differsntiation
