该基因属于转录因子的叉头家族，具有独特的叉头结构域。该基因可能通过表达细胞死亡所需的基因来触发细胞凋亡。该基因与MLL基因易位与继发性急性白血病有关。另外，还观察到编码相同蛋白质的剪接转录变体。
This gene belongs to the forkhead family of transcription factors which are characterized by a distinct forkhead domain. This gene likely functions as a trigger for apoptosis through expression of genes necessary for cell death. Translocation of this gene with the MLL gene is associated with secondary acute leukemia. Alternatively spliced transcript variants encoding the same protein have been observed.
