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
RB and cell cycle progression Biology Diagrams
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. The role of RB in cell cycle control Prog Cell Cycle Res. 1995:1:9-19. doi: 10.1007/978-1-4615-1809-9_2. Authors M
Loss of cell-cycle control is a hallmark of neoplastic cells. One regulator of the critical G1 to S-phase transition in the cell cycle is the retinoblastoma tumour suppressor protein Rb, which 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. The mechanisms of
PDF The role of RB in cell cycle control 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.
