Fusion proteins were generated between the human 5-hydroxytryptamine (5-HT)(1A) receptor and both wild-type (Cys(351)) and pertussis toxin-resistant (Gly(351) and Ile(351)) forms of G(i1). These were expressed stably. Pertussis toxin treatment substantially reduced basal high-affinity GTPase activity in clones expressing the 5-HT(1A) receptor wild-type(More)
A cDNA encoding the mouse delta opioid receptor was expressed stably in a Rat 1 fibroblast cell line. Expression of this receptor was demonstrated both in ligand binding studies and by reverse transcriptase-PCR. In membranes of clone D2 cells the opioid peptide [D-Ala(2)]-leucine enkephalin (DADLE) produced a robust, concentration-dependent, stimulation of(More)
Recombinant RGS1, RGS16 and RGS-GAIP, but not RGS2, were able to substantially further stimulate the maximal GTPase activity of G(o1)alpha promoted by agonists at the alpha2A-adrenoreceptor in a concentration-dependent manner. Kinetic analysis of the regulation of an alpha2A-adrenoreceptor-G(o1)alpha fusion protein by all three RGS proteins revealed that(More)
We present a stratification of the genetic basis of primary ciliary dyskinesia (PCD), based on screening >230 individuals for gene mutations using various approaches including whole exome sequencing. PCD is a genetically heterogeneous recessive ciliopathy, characterized by chronic lung disease and laterality and fertility defects arising from cilia and(More)
