TP53I3 is similar to oxidoreductases, enzymes that play a role in cellular responses to oxidative stress and irradiation . The protein is involved in p53-mediated cell death, which is a critical mechanism for preventing the proliferation of cells with damaged DNA . When cells are exposed to genotoxic agents, TP53I3 is localized to the cytoplasm and is induced in both primary and transformed cell cultures .
The TP53 gene, which encodes the p53 protein, is mutated in approximately half of all human cancers . Mutations in this gene often lead to the loss of p53’s tumor-suppressing functions, resulting in uncontrolled cell proliferation and tumor development . TP53I3, being a downstream target of p53, is also implicated in these processes. The protein’s role in oxidative stress response and apoptosis makes it a significant player in the cellular mechanisms that prevent cancer progression .
Given its involvement in p53-mediated pathways, TP53I3 is a subject of interest in cancer research. Understanding its function and regulation could lead to new therapeutic strategies aimed at restoring p53’s tumor-suppressing activities in cancers where TP53 is mutated . Additionally, TP53I3’s role in oxidative stress response suggests potential applications in therapies targeting cellular redox balance .
