The p53 protein functions as an activator of
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. Webb11 apr. 2024 · Yeasts have been a part of human life since ancient times in the fermentation of many natural products used for food. In addition, in the 20th century, they became powerful tools to elucidate the functions of eukaryotic cells as soon as the techniques of molecular biology developed. Our molecular understandings of …
