Bone Morphogenetic Proteins (BMPs) are morphogens that play a major role in regulating development and homeostasis. Although BMPs are used for the treatment of bone and kidney disorders, their clinical use is limited due to the supra-physiological doses required for therapeutic efficacy causing severe side effects. Because recombinant BMPs are expensive to(More)

The five muscarinic acetylcholine receptors (M(1)-M(5)) are prototypical members of the superfamily of G-protein-coupled receptors (GPCRs). During the past decade, this laboratory has used different members of this receptor subfamily as model systems to study the molecular mechanisms involved in GPCR function. This article reviews recent investigations(More)
The N termini of two G protein alpha subunits, alphaq and alpha11, differ from those of other alpha subunits in that they display a unique, highly conserved six-amino acid extension (MTLESI(M)). We recently showed that an alphaq deletion mutant lacking these six amino acids (in contrast to wild type alphaq) was able to couple to several different Gs- and(More)
Most G protein-coupled receptors contain a conserved pair of extracellular cysteine residues that are predicted to form a disulfide bond linking the first and second extracellular loops. Previous studies have shown that this disulfide bond may be critical for ligand binding, receptor activation, and/or proper receptor folding. However, the potential(More)
The structural basis underlying the G protein coupling selectivity of different muscarinic receptor subtypes was analyzed by using a combined molecular genetic/biochemical approach. These studies led to the identification of key residues on the receptors as well as the associated G proteins that are critically involved in determining proper receptor/G(More)
