Mutagenesis of the beta2-Adrenergic Receptor: How Structure Elucidates Function

Autor: Robert J. Lefkowitz, J Ostrowski, Michael A. Kjelsberg, Marc G. Caron

Publikováno v: Annual Review of Pharmacology and Toxicology. 32:167-183

Accurate responses to extracellular stimuli are one of the most important physiological reactions in every living cell. To accomplish that goal, each cell has developed on its surface numerous highly specialized receptors responsi ble for transmitt

Discrete amino acid sequences of the alpha 1-adrenergic receptor determine the selectivity of coupling to phosphatidylinositol hydrolysis

Autor: Michael A. Kjelsberg, Marc G. Caron, Robert J. Lefkowitz, J Ostrowski, Susanna Cotecchia

Publikováno v: Journal of Biological Chemistry. 267:1633-1639

We have constructed a variety of chimeric beta 2/alpha 1 adrenergic receptors (AR) in which selected portions of the third intracellular loop of the alpha (1B)AR were substituted into the corresponding regions of the beta 2AR. The mutant receptors we

Constitutive activation of the alpha 1B-adrenergic receptor by all amino acid substitutions at a single site. Evidence for a region which constrains receptor activation

Autor: Michael A. Kjelsberg, J Ostrowski, Marc G. Caron, Robert J. Lefkowitz, Susanna Cotecchia

Publikováno v: Journal of Biological Chemistry. 267:1430-1433

Mutations in an intracellular region of the alpha 1B-adrenergic receptor constitutively activate the receptor, resulting in G protein coupling in the absence of agonist, as evidenced by elevated levels of polyphosphoinositide hydrolysis. Remarkably,

Publikováno v: Vascular medicine (London, England). 8(1)

Inflammation plays a central role in restenosis following coronary intervention. Recent human and animal data suggest important differences between the inflammatory responses to simple balloon angioplasty compared with stent implantation. To investig
