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. WebbWhile p53 activity is controlled by post-translational modification of the protein, such as phosphorylation and acetylation, the abundance of p53 protein is strictly regulated by the ubiquitin proteasomal pathway. Under unstressed conditions, the half-life of p53 protein is 5–20 min [ 15, 41, 42, 43 ]. the paddock rutlandWebb24 aug. 2024 · The human P53 is widely acknowledged as an intra-nuclear phosphorylated protein. The wide type P53 normally exists in the nucleus for an extremely short period [ 16 ]. On the other hand, the mutated P53 has a prolonged half-life to 20–40 h as it is not digested quickly and therefore accumulates inside tumor cells [ 17 ]. the paddocks aldbourne
