Recent years have seen tremendous progress in the field of hormone
action and consequent signal transduction. The 40th Colloquium Mosbach
was devoted to the discussion of results concerning the molecular
process of hormone action, especially the processes following hormone
binding to the corresponding receptors. Structural and functional
aspects of steroid hormone receptors as well as ion-channel-coupled and
enzyme-linked receptors were treated in detail. Particular interest
focussed on the latest results concerning transcriptional control,
protein phosphorylation, the role of G-Proteins, oncogene proteins,
involvement of phospholipases and the regulation of ion channels.
