GenAge entry for RB1 (Homo sapiens)

Gene name (HAGRID: 120)

HGNC symbol: RB1
Aliases: RB; PPP1R130; OSRC
Common name: retinoblastoma 1

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence directly linking the gene product to ageing in a cellular model system
Description: RB1 is a tumour suppressor that acts as a transcriptional regulator to control cell cycle progression. Mice with disrupted RB1 are not viable [605]. Mutations in the human RB1 gene have been associated with cancer [991]. Clearly, RB1 plays a role in cellular senescence and oncogenesis [95], but it is unknown whether it influences human ageing.
