p53基因编码的蛋白质
英文回答:
The p53 gene encodes a protein that is a tumor suppressor. This protein is activated in response to various cellular stresses, such as DNA damage, oxidative stress, and oncogene activation. Once activated, p53 triggers a number of cellular responses, including cell cycle arrest, DNA repair, and apoptosis.
p53 is a transcription factor that regulates the expression of a number of genes. These genes are involved in a variety of cellular processes, including cell cycle regulation, DNA repair, and apoptosis. p53 also interacts with a number of other proteins, which help to mediate its effects on cell fate.
Mutations in the p53 gene are common in cancer. These mutations can result in the loss of p53 function, which allows cancer cells to grow and proliferate unchecked. p53
mutations are also associated with resistance to chemotherapy and radiation therapy.
