Webb5 nov. 2008 · T-2 toxin is a cytotoxic secondary fungal metabolite that belongs to the trichothecene mycotoxin family. This mycotoxin is a well known inhibitor of protein synthesis through its high binding affinity to peptidyl transferase, which is an integral part of the ribosomal 60s subunit, and it also inhibits the synthesis of DNA and RNA, probably … WebbBesides apoptosis and the cell cycle, p53 also controls other processes, such as senescence, 17 autophagy, 18, 19 angiogenesis, 20 and DNA repair. 21 Given its key role in protecting cells, p53 activation is tightly regulated. Indeed, the half-life of p53 is short under normal conditions, and is regulated by numerous E3 and E4 ligases.
