The protein encoded by this gene is a negative regulator of the cell cycle and was the first tumor suppressor gene found. The encoded protein also stabilizes constitutive heterochromatin to maintain the overall chromatin structure. The active, hypophosphorylated form of the protein binds transcription factor E2F1. Defects in this gene are a cause of childhood cancer retinoblastoma (RB), bladder cancer, and osteogenic sarcoma. [provided by RefSeq, Jul 2008]
由该基因编码的蛋白质是细胞周期的负调节和是发现的第一个肿瘤抑制基因。所编码的蛋白质也稳定结构异保持整体染色质结构。该蛋白质的活性,低磷酸形式结合转录因子E2F1。在该基因缺陷的儿童癌症视网膜母细胞瘤(RB),膀胱癌和骨肉瘤的一个原因。 [由RefSeq的,2008年7月提供]
