A study of Puf-A in zebrafish has shown that Puf-A is highly expressed in primordial germ cells (PGCs) and participates in PGC development. However, it remains unclear how Puf-A governs PGC development in mammals. Here, we generated transgenic mice carrying …
Webp53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates, where they prevent cancer formation. As such, p53 has … WebMar 1, 2024 · PTMs can be specific to the type of DNA damage 120, 121, 122, 123, 124, 125, 126 and thus can accordingly direct the p53-mediated response and cell fate.
