| + | [[http://www.uniprot.org/uniprot/MED23_HUMAN MED23_HUMAN]] Required for transcriptional activation subsequent to the assembly of the pre-initiation complex (By similarity). Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional pre-initiation complex with RNA polymerase II and the general transcription factors. Required for transcriptional activation by adenovirus E1A protein. Required for ELK1-dependent transcriptional activation in response to activated Ras signaling.<ref>PMID:10353252</ref> <ref>PMID:14759369</ref> <ref>PMID:16595664</ref> | ||

| + | Sur2 is a metazoan Mediator subunit that interacts with the adenovirus E1A protein and functions in a mitogen-activated protein kinase pathway required for vulva development in Caenorhabditis elegans. We generated sur2-/- embryonic stem cells to analyze its function as a mammalian Mediator component. Our results show that Sur2 forms a subcomplex of the Mediator with two other subunits, TRAP/Med100 and 95. Knock-out of Sur2 prevents activation by E1A-CR3 and the mitogen-activated protein kinase-regulated ETS transcription factor Elk-1, but not by multiple other transcription factors. These results imply that specific activation domains stimulate transcription by binding to distinct Mediator subunits. Activation by E1A and Elk-1 requires recruitment of Mediator to a promoter by binding to its Sur2 subunit. | ||
