该基因是转录因子DP家族的成员编码蛋白与E2F转录因子形成异二聚体，导致细胞周期调控基因的转录激活。选择性剪接导致多个转录变体[由RefSeq提供，2010年5月]
The gene is a member of the transcription factor DP family. The encoded protein forms heterodimers with the E2F transcription factors resulting in transcriptional activation of cell cycle regulated genes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]
