Although the retinoblastoma-susceptibility gene RB1 is inactivated in a wide range of human tumours, in colorectal cancer, the retinoblastoma protein (Rb) function is often preserved and the RB ...

When the retinoblastoma protein is phosphorylated, the gate is open and the cell cycle proceeds to cell division; the gate closes when the phosphates are removed. Rubin’s team used x-ray ...
