Reproduction: The unusual suspect
Colin L. Stewart1
Abstract
The p53 protein is widely studied for its function as a tumour suppressor, preventing cancer. It emerges that this protein also has an essential physiological role in regulating embryo implantation in mice.
The p53 protein, which has been given the accolade 'guardian of the genome', is a celebrity among cellular proteins. If you search the PubMed database for p53, you'll get more than 44,000 hits, the vast majority of which discuss the role of this protein in protecting cells from the consequences of stress-induced DNA damage.
