Interactions of the GnRH receptor with heterotrimeric G proteins

Front Neuroendocrinol. 2013 Apr;34(2):88-94. doi: 10.1016/j.yfrne.2012.11.001. Epub 2012 Nov 27.

Abstract

G protein-coupled receptors (GPCRs) are the largest class of integral membrane protein receptors in the human genome. We examined here the reports whether the GnRH receptor (GnRHR) interacts with a single or multiple types of G proteins. It seems that the GnRHR, as other GPCRs, alternates between various conformations and is stabilized by its ligands, other modulators and intracellular partners in selective conformations culminating in coupling with a single type or multiple G proteins in a cell- and context-specific manner.
