Webb15 apr. 2000 · 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. Previous article Next article Keywords Cell … WebbNormally, wild-type p53 protein (wtp53) is either degraded or bound to a negative regulator and is inactive. When damage to DNA occurs within a cell, p53 protein is induced and causes cell cycle arrest. This gives cells a chance to repair, but if damage is too severe, cells undergo apoptosis and are rejected. ironing boards for pants

Webb31 aug. 1990 · However, the role of the wild-type p53 gene in growth control is not known. Hybrid proteins that contain the DNA binding domain of yeast GAL4 and portions of p53 have been used to show that the p53 protein contains a transcription-activating sequence that functions in both yeast and mammalian cells. Webb4 okt. 2009 · The human gene that encodes p53, TP53, was uncovered in 1984. We now know that one of p53’s key jobs is to act as a ‘transcription factor’, responsible for turning genes on in response to DNA damage. This has earned p53 …
