MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygotes for targeted mutations exhibit abnormalities of the neuronal and hematopoietic systems and die in utero. Heterozygotes may develop pituitary tumors associated with loss of the normal allele. [provided by MGI curators]
