该基因编码一个转录因子家族的成员，该转录因子与E2F蛋白异二聚体以增强其DNA结合活性并促进来自E2F靶基因的转录编码的蛋白质作为这个复合物的一部分，控制着许多参与细胞周期从g1期到s期进展的基因的转录活性。选择性剪接导致多个转录变体该基因的假基因存在于1号、15号和X号染色体上。[由RefSeq提供，2009年1月]
This gene encodes a member of a family of transcription factors that heterodimerize with E2F proteins to enhance their DNA-binding activity and promote transcription from E2F target genes. The encoded protein functions as part of this complex to control the transcriptional activity of numerous genes involved in cell cycle progression from G1 to S phase. Alternative splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 1, 15, and X.[provided by RefSeq, Jan 2009]
