These gene products can also be mutated by carcinogenic agents The pprotein is a transcription factor that can activate the expression of multiple target genes and plays critical roles in regulating cell cycle, apoptosis, and genomic stability, and is The tumour suppressor phas a central role in the response to cellular stress. If a person inherits only one functional copy of the pgene from their parents, they are predisposed to cancer and usually develop several independent tumors in a variety of tissues in early adulthood Tumor Suppressor gene products like pfrequently suppress mitosis and cell growth to allow for DNA repair. Activated ptranscriptionally regulates hundreds of genes that are involved in multiple biological If a person inherits only one functional copy of the pgene from their parents, they are predisposed to cancer and usually develop several independent tumors in a variety of pis a tumor suppressor protein that regulates cell division and prevents tumor formation by stopping cells with mutated or damaged DNA from dividing and signaling for them to undergo apoptosis through transcriptional regulation The ptumor suppressor protein. We describe here the paradox of how, depending on its muta-tional status in cancer, pis a tumor suppressor protein that regulates cell division and prevents tumor formation by stopping cells with mutated or damaged DNA from dividing and signaling for them to undergo apoptosis through transcriptional regulation Transactivation of the mdm2 gene by pactivates expression of the mdm2 protein, which binds to an amino terminal domain of pand inactivates its transactivation function, 4l thus providing for an autoregulatory feedback loop The ptumor suppressor protein. If a person inherits only one functional copy of the pgene from their parents, they are predisposed to cancer and usually The pgene is a tumor suppressor gene and its activity stops the formation of tumors. gene, encoding p53, was voted the most ‘‘popular’’ human geneNow, on theth anniversary of Cell, we reflect on what we have learned about pafter all this attention. The pgene like the Rb gene, is a tumor suppressor gene, i.e., its activity stops the formation of tumors. The pgene like the Rb gene, is a tumor suppressor gene, i.e., its activity stops the formation of tumors.
