p53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates , where they prevent cancer formation. [ 5 ]
Each assay may give different results of the clinical value of the p53 mutations as a prognostic factor. [6] Interlaboratory proficiency testing for tumor marker tests, and for clinical tests more generally, is routine in Europe and an emerging field [7] in the United States. New York state is prominent in advocating such research. [8]
p53 can be activated in response to a wide variety of cellular stressors, both oncogenic and non-oncogenic. An important checkpoint in a complex pathway, activated p53 has been shown to bind DNA and transcriptionally regulate genes that can mediate a variety of cellular growth processes including DNA repair , growth arrest, cellular senescence ...
One such example of the regulatory role that phosphorylation plays is the p53 tumor suppressor protein. The p53 protein is heavily regulated [28] and contains more than 18 different phosphorylation sites. Activation of p53 can lead to cell cycle arrest, which can be reversed under some circumstances, or apoptotic cell death. [29]
Tumor suppressor p53-binding protein 1 also known as p53-binding protein 1 or 53BP1 is a protein that in humans is encoded by the TP53BP1 gene. [ 5 ] [ 6 ] [ 7 ] Clinical significance
Observations show that E1b-55k inhibits activation by p53 by binding a repression domain to it, converting it from an activator to a repressor of p53-activated genes. This stabilizes p53 and causes a large increase in p53 concentration. Additionally, p53 bound to E1B-55k has an affinity for its binding site that is ten times higher than free ...

Lymphocytes can enter mitosis when they are activated by mitogens or antigens. B cells specifically can divide when they encounter an antigen matching their immunoglobulin . T cells undergo mitosis when stimulated by mitogens to produce small lymphocytes that are then responsible for the production of lymphokines , which are substances that ...
