Abstract:Mutations in the DNA binding region of tumor suppressor p53 render it transcriptionally inactive (dominant negative) but can also manifest in transcriptionally-independent gain-of-function (GOF) effects, possibly due to mutp53 interacting with other, as yet, unknown targets. Identification of these targets would help to elucidate the pathways and vulnerabilities involved in mutp53 GOF. Covalently linking a known handle to these unknown proteins is one method to aid in their isolation and identification. A hydr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
