Which of the following is characteristic of the product of
It is an activator of other genes and is characteristic of the product of the p53 gene. Several pro-apoptotic BCL-2 family members, including. BAX, 41, 42, 43, BBC3 (PUMA), 181 and PMAIP1 (NOXA), 182, are activated by p53. When released from mitochondria, cytochrome c binds to APAF1 and procaspase-9 to form apoptosomes. APAF1 is also activated.

TP53 gene: MedlinePlus Genetics
Normal Function The TP53 gene provides instructions for making a protein called tumor protein p53 (or p53). This protein acts as a tumor suppressor, which means that it regulates cell division by keeping cells from growing and dividing (proliferating) too fast or in an uncontrolled way.
The p53 tumor suppressor protein Genes and Disease
< Prev Next > The p53 gene like the Rb gene, is a tumor suppressor gene, i.e., its activity stops the formation of tumors. If a person inherits only one functional copy of the p53 gene from their parents, they are predisposed to cancer and usually develop several independent tumors in a variety of tissues in early adulthood.
Targeting p53 pathways: mechanisms, structures, and advances
The p53 protein 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.
Exploring the multiple roles of guardian of the genome: P53
Background Cells have evolved balanced mechanisms to protect themselves by initiating a specific response to a variety of stress. The TP53 gene, encoding P53 protein, is one of the many widely studied genes in human cells owing to its multifaceted functions and complex dynamics. The tumour-suppressing activity of P53 plays a principal role in the cellular response to stress. The majority of.
Mutant p53 in cancer: from molecular mechanism to
TP53, a crucial tumor suppressor gene, is the most commonly mutated gene in human cancers. Aside from losing its tumor suppressor function, mutant p53 (mutp53) often acquires inherent, novel.
Function of the p53 gene: choice between life and death
Multiple signal pathways monitor the state of a cell and when damage or a fault is found that could cause heritable changes, p53 protein is activated to either coordinate the repair process or induce cell suicide. Thus, the p53 gene acts as a supreme judge that decides the fate of cells and guarantees their social behavior.
