WebJul 16, 2024 · The p53 protein, made by the TP53 gene, normally acts as the supervisor in the cell as the body tries to repair damaged DNA. Different mutations can determine how well or how poorly that supervisor is able to direct the response. The more defective the mutation, the greater the risk. WebJan 3, 2024 · Identified in the late 1970s as an oncogene, a driving force leading to tumor development, p53 turned out to be a key tumor suppressor gene. Now p53 is considered a master gene regulating the transcription of over 3000 target genes and controlling a remarkable number of cellular functions. The elevated prevalence of p53 mutations in …
WebIn 2004 has been found that one of ARF's p53-independent functions involves its binding to nucleophosmin /B23 (NPM). [9] NPM is an acidic ribosomal chaperone (protein) involved in preribosomal processing and nuclear exportation independent of p53, and oligomerizes with itself and p14 ARF.
WebNational Center for Biotechnology Information WebJan 18, 2024 · Introduction. p53, encoded by the TP53 gene, is a critical tumor suppressor that is required to prevent the oncogenic transformation of cells. Of note, TP53 is the most frequently mutated gene in human cancers, and in most cases, TP53 mutation is associated with poor prognosis (Levine, 2024; Olivier et al., 2010).Mutant p53 (Mutp53) proteins not …
WebWhile p53 is the most frequently mutated gene in human tumors, p73 and p63 are rarely mutated or lost in cancers. Although p53-deficient cancer cells are often less responsive to chemotherapy, they are not completely drug resistant, suggesting that other apoptotic pathways are at work.
