Fig. 4.10. Principle of signal transduction by steroid hormone receptors. The steroid hormone receptors in the cytosol are found in the form of an inactive complex with the heat shock proteins Hsp90 and Hsp56 and with protein p23. The binding of the hormone activates the receptor so that it can be transported into the nucleus where it binds to its cognate HRE. It remains unclear in which form the receptor is transported into the nucleus, and to which extent the associated proteins are involved in the transport. One mechanism of activation of transcription initiation involves activation of a histone acetylase and remodehng of chromatin. Furthermore, the receptors interact directly or indirectly with components of the RNA polymerase II holoenzyme (e.g. SUGl).
