Using three different approaches to functionally inactivate Mediator ( immunoneutralization, immunodepletion, and inhibitory polypeptides ), we find that

Santanavanich et al., J Pineal Res 2005
:
Taken together with our previous data, the results indicate that activation of D1-dopamine receptor in bovine pinealocyte stimulates

enhances melatonin level whereas activation of

Ca2+ dependent
NAT
Liu et al., Mol Cell Biol 2008
:
STAF65gamma is
required for SPT3/STAGA interaction with core
Mediator and for MYC recruitment of SPT3, TAF9, and core Mediator components to the TERT promoter but is dispensable for MYC recruitment of TRRAP, GCN5, and p300 and for acetylation of nucleosomes and loading of TFIID and RNA polymerase II on the promoter
Ge et al., Mol Cell Biol 2008
:
These results indicate that there is a conditional requirement for MED1/TRAP220 and that a direct interaction between PPARgamma and
Mediator through MED1/TRAP220 is not
essential either for PPARgamma stimulated adipogenesis or for
PPARgamma target gene expression in cultured fibroblasts ... As
Mediator is apparently
essential for
PPARgamma transcriptional activity, our data indicate the presence of alternative mechanisms for Mediator recruitment, possibly through intermediate cofactors or other cofactors that are functionally redundant with MED1/TRAP220

NAT regulates
E-cadherin expression

stimulation of

stimulation of
