abstract = {GABAB receptors are seven-transmembrane G-protein-coupled
receptors (GPCRs) for γ-aminobutyric acid (GABA), the most
abundant inhibitory neurotransmitter in the central nervous
system. They couple to a variety of signalling pathways and
thereby serve diverse functions. In humans, GABAB receptors
are implicated in a number of psychiatriac and neurological
diseases. GABAB receptors function as obligate heteromers
consisting of the two subunits, GB1 and GB2, whereby GB1
binds the ligand and GB2 is coupled to the G protein. This
unique functional principle is phylogenetically conserved
and can be found in both deuterostomes and protostomes.
Nevertheless, remarkable differences in the pharmacological
properties do exist between species. In this study, we aimed
to investigate the functionality and the pharmacological
profile of an interspecies GABAB receptor heteromer,
consisting of the GB1 subunit from the American cockroach
Periplaneta americana and the GB2 subunit of the fruit fly
Drosophila melanogaster. Co-expression of both proteins in a
heterologous expression system indeed lead to the formation
of functional receptor heteromers. Activation of
interspecies heterodimers caused a dose-dependent decrease
in the production of cAMP. Moreover, we demonstrate that GB2
modulates not only the potency but also the efficacy of
ligand binding.},
