... Rb is a tumor suppressor gene because its loss-of-function causes cancer. Also, the Rb gene product‘s normal function is to inhibit the transcription of genes necessary for continuation through the cell cycle; thus it inhibits cell division and can be thought of as a tumor suppressor for that reason ...
