The TP53 is a gene that instructs the cell to produce tumor protein (p53) ; a vital transcription factor and tumor suppressor. P53 is known as the “guardian of the genome” as it helps in regulating the cell cycle and acts as a tumor suppressor.

Is TP53 and p53 the same?
p53, also known as TP53 or tumor protein (EC :2.7. 1.37) is a gene that codes for a protein that regulates the cell cycle and hence functions as a tumor suppression. It is very important for cells in multicellular organisms to suppress cancer.
What does the TP53 gene do?
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.
What are the 3 types of cancer genes?
About genetic mutations
- Acquired mutations. These are the most common cause of cancer. ...
- Germline mutations. These are less common. ...
- Tumor suppressor genes. These are protective genes. ...
- Oncogenes. These turn a healthy cell into a cancerous cell. ...
- DNA repair genes. These fix mistakes made when DNA is copied.
How is the p53 gene related to cancer?
A gene that makes a protein that is found inside the nucleus of cells and plays a key role in controlling cell division and cell death. Mutations (changes) in the p53 gene may cause cancer cells to grow and spread in the body.
What cancers is p53 associated with?
P53 mutations associated with breast, colorectal, liver, lung, and ovarian cancers.
How is p53 inactivated?
p53 pathway: In a normal cell, p53 is inactivated by its negative regulator, mdm2. Upon DNA damage or other stresses, various pathways will lead to the dissociation of the p53 and mdm2 complex.
Is p53 good or bad?
As these data suggest, p53 is of principal importance in sensing DNA damage, telomeric shortening, and oxidative stress (and in particular, its activity is regulated by the latter), and it seems clear that p53, acting as a “bad cop,” contributes to mammalian aging.
When is p53 activated?
The tumour suppressor protein p53 is stabilised and activated in response to ionising radiation. This is known to depend on the kinase ATM; recent results suggest ATM acts via the downstream kinase Chk2/hCds1, which stabilises p53 at least in part by direct phosphorylation of residue serine 20.
How common is p53 mutation?
The p53 gene contains homozygous mutations in ~50–60% of human cancers. About 90% of these mutations encode missense mutant proteins that span ~190 different codons localized in the DNA-binding domain of the gene and protein.
Will I get cancer if my dad had it?
This means the cells may become cancerous. We inherit genes from both our parents. If a parent has a gene fault then each child has a 1 in 2 chance (50%) of inheriting it. So some children will have the faulty gene and an increased risk of developing cancer and some children won't.
Will I get cancer if my mom had it?
'” Yes, cancer is due to genetic changes, but that doesn't generally mean it's inherited. “We see a huge amount of confusion about this,” says Katherine Nathanson, MD, Associate Professor of Genetics at Penn Medicine. “There is an inherited variation in different genes, which can lead to cancer that runs in families.
Can cancer be passed down genetically?
Although cancer is common, only 5-10% of it is hereditary, meaning an individual has inherited an increased risk for cancer from one of their parents. This inherited risk for cancer is caused by a small change (called a mutation) in a gene, which can be passed from one generation to the next in a family.
