In this study we sought to determine the role of the cohesin and Mediator complexes in controlling estrogen-dependent gene transcription.
Recently, Eric Olson's group reported that the heart controls systemic energy metabolism, fat mass, and body weight via microRNA-208a (miR-208a) and Mediator complex subunit 13 (MED13) signaling (Grueter et al, 2012).
Recent studies have revealed that specific interactions between transcription factors and several well-defined Mediator subunits control a wide range of physiological functions; however, the functions and mechanisms of the Mediator complex in the development of different metabolic diseases remain to be elucidated.
The Mediator complex: a central integrator of transcription.
BRD4 is known to be involved in transcriptional control by regulating the release of paused RNA polymerase II via interaction with P-TEFb, and by association with the Mediator complex.
These SEs are densely loaded with the Mediator complex, master TFs, and chromatin regulators17,18,19,20.
The Mediator complex: a master coordinator of transcription and cell lineage development.
Bhagwat, A. S. et al. BET bromodomain inhibition releases the Mediator complex from select cis-regulatory elements.
Kim JH, Yang CK, Heo K, Roeder RG, An W, Stallcup MR. CCAR1, a key regulator of mediator complex recruitment to nuclear receptor transcription complexes.
The metabolic functions of the Mediator complex have become increasingly significant.
