Paulino AC. … The retinoblastoma protein (protein name abbreviated Rb; gene name abbreviated Rb, RB or RB1) is a proto-oncogenic tumor suppressor protein that is dysfunctional in several major cancers. One function of pRb is to prevent excessive cell growth by inhibiting cell cycle progression until a … See more In humans, the protein is encoded by the RB1 gene located on chromosome 13—more specifically, 13q14.1-q14.2. If both alleles of this gene are mutated early in life, the protein is inactivated and results in development of See more pRb restricts the cell's ability to replicate DNA by preventing its progression from the G1 (first gap phase) to S (synthesis phase) phase of the cell division cycle. pRb binds and inhibits E2 promoter-binding–protein-dimerization partner (E2F-DP) dimers, which are See more When it is time for a cell to enter S phase, complexes of cyclin-dependent kinases (CDK) and cyclins phosphorylate pRb, allowing E2F-DP to dissociate from pRb and become active. … See more The classic view of pRb's role as a tumor suppressor and cell cycle regulator developed through research investigating mechanisms of interactions with E2F family member proteins. Yet, more data generated from biochemical experiments and clinical trials … See more pRb is a multifunctional protein with many binding and phosphorylation sites. Although its common function is seen as binding and repressing E2F targets, pRb is likely a multifunctional protein as it binds to at least 100 other proteins. pRb has three … See more Senescence in cells is a state in which cells are metabolically active but are no longer able to replicate. pRb is an important regulator of senescence in cells and since this prevents proliferation, senescence is an important antitumor mechanism. pRb … See more Consequences of loss of pRb function is dependent on cell type and cell cycle status, as pRb's tumor suppressive role changes depending on the state and current identity of the cell. In G0 quiescent stem cells, pRb is proposed to … See more
