Cell growth dilutes the cell cycle inhibitor Rb to trigger cell Biology Diagrams The RB gene was cloned more than 25 years ago 1.Since that time, its encoded protein has been identified as a universal cell cycle regulator with a central role in controlling the commitment of a cell to initiate DNA replication and divide 2.Eliminating RB function allows unregulated cell cycle progression and promotes tumour growth.

The retinoblastoma protein is an inhibitor of cell cycle progression from the G1 to the S phase of the cell cycle. It acts through its ability to interact with cellular target molecules such as E2F transcription factors. Hatakeyama, M., Weinberg, R.A. (1995). The role of RB in cell cycle control. In: Meijer, L., Guidet, S., Tung, H.Y.L Rb family proteins (pRb/p105, Rb2/p130 and p107) play a key role in cell cycle control and are worthily involved in transcription repression and tumor suppression.

cycle regulation and apoptosis Biology Diagrams
The Rb protein is a tumor suppressor, which plays a pivotal role in the negative control of the cell cycle and in tumor progression. It has been shown that Rb protein (pRb) is responsible for a major G1 checkpoint, blocking S-phase entry and cell growth. The retinoblastoma family includes three memb โฆ The retinoblastoma (RB) family of proteins are found in organisms as distantly related as humans, plants, and insects. These proteins play a key role in regulating advancement of the cell division cycle from the G1 to S-phases. This is achieved through negative regulation of two important positive regulators of cell cycle entry, E2F transcription factors and cyclin dependent kinases.
