Transmembrane Signaling by GPCRs and Channels
Organizer(s): Oliver P. Ernst and U. Benjamin Kaupp
Date: January 23 - 28, 2011
Location: Sagebrush Inn & Suites, Taos, NM, USA
Sponsored by Takeda Pharmaceutical Company Limited
Summary of Meeting:
Cellular membranes present natural borders for signal transduction between cells and their environment. Nature developed different strategies to enable signals to cross the membrane barrier. The goal of this meeting is to discuss the molecular mechanisms of transmembrane signaling on the basis of three protein classes, i.e. G protein-coupled receptors, ion channels and transporters. Available protein structures together with biophysical and functional approaches will provide guidance to explore similarities and differences of the underlying mechanisms. Exemplified will be receptors and channels as well as proteins with dual or modified functions, such as channelrhodopsin. A comparative view is thought to bring researchers from diverse fields together and to stimulate further development of transmembrane signaling proteins in drug discovery and fighting disease.
