If there is a mutation in the p53 gene, leading to a mutated p53 protein, this can have serious health implications – in fact, p53 is the most frequently inactivated gene in all human cancers [2].
Without functioning p53, cell proliferation is not regulated. p53, guardian of the genome. 1992 Jul 2;358(6381):15-6. Nature. p53, guardian of the genome. [/su_youtube] p53 GENE This is a tumor suppressor gene ( its activity stops the formation of tumors) Located on 17p13, first discovered in 1979 The p53 protein is the product of p53 gene P-protein 53- weight of the protein, 53 kDa Located in almost all normal tissues Unstable and …
Tumor protein p53, also known as p53, cellular tumor antigen p53 (UniProt name), the Guardian of the Genome, phosphoprotein p53, tumor suppressor p53, antigen NY-CO-13, or transformation-related protein 53 (TRP53), is any isoform of a protein encoded by homologous genes in various organisms, such as TP53 (humans) and Trp53 (mice). Show details Nature Actions. P53 - The Guardian of the Genome p21 Transcribed by p53 p53+ p21 complex stops cell cycle Cell cycle stopped until DNA repaired (Vijayaraj and Kumar) MDM2 p53 Mutations Functions of p53 Major p53 regulator Triggers degradation of p53 (Vijayaraj and Kumar) Relation of p53 to Human Guardian of the genome: P53 application guide. Most of the TP53 gene mutations involved in HNSCC change single amino acids in p53; these changes impair the protein's function.

This type of cancerous tumor occurs in the moist lining of the mouth, nose, and throat. Infographic: P53- Guardian of the Genome. The p53 regulatory network, the 'guardian of the genome' has, during the course of human evolution, created additional safeguards in human genes to further guard against DNA damage that could a variety of genetic diseases, according to an international team of scientists writing in the Proceedings of the National Academy of Sciences.
p53 'Guardian of the Genome' and 'Policeman of the Oncogenes' p53: 53 Kd (kilodalton) tumor suppressor protein known as TP53 coded by tumor suppresser gene p53.
This homolog (originally thought to be, and often spoken of … P53 – Guardian of the genome Its structure is well characterised, over 100 proteins have been identified as interacting with it, more than 50 different types of cancer show compromised function of it and a pubmed search for ‘p53’ brings up over 70,000 articles. What is the link between genes and cancer? In this infographic, we explore how malfunctions in a regulatory gene, called p53, can increase susceptibility to some forms of cancer.
The important role p53 appears to play in cancer prevention earned it the nickname of “guardian of the genome”.

Therefore, the regulation of this critical mtDNA factor p53 as guardian of the mitochondrial genome J.-H. Park et al. Lane DP. It should be noted here that p53 has also been shown to interact with mitochondrial matrix-localized TFAM protein as will be discussed later in this review [38].
