Abstract:1302
The mammalian multi-protein complex Mediator, originally identified by ourselves as a nuclear receptor-specific coactivator complex, is a phylogenetically-conserved subcomplex of the RNA polymerase II holoenzyme and serves as an end-point integrator of diverse intracellular signals and transcriptional activators. The 220-kDa Mediator subunit MED1 is a specific coactivator not only for nuclear receptors but for GATA family activators, and serves as a GATA1-specific coactivator that is essent… 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.
