βarr is a signaling molecule in its own right, capable of activating molecular pathways that Assessing GPCR Signaling with Impedance Profiles Journal of Biomolecular Screening 14(3); 2009 www.sbsonline.org 249 diversity. In contrast, impedance assays can detect activation of Gs, Gi, and Gq pathways and thus have the potential to readily detect cell-specific differences in G-protein coupling. For impedance (–10 In addition to c-Src activation, β-arrestin has been shown in multiple studies to function as a signaling intermediate in GPCR signal transduction to mitogen-activated protein kinase (MAPK) pathways, under conditions where G protein coupling is virtually absent. 125,128,129 Although this β-arrestin–dependent signaling has been most well characterized for ERK activation, it may also apply GPCR signaling leads to the activation of G proteins, Src familiy kinases, PKC, and PI-3 Kinase.

Gpcr signaling

GPCR function is associated with cell sensing of external factors including odorants, taste ligands, light, metals, neurotransmitters, biogenic amines, fatty acids, amino acids, peptides, proteins, steroids and other lipids. Se hela listan på azolifesciences.com Select GPCRs exhibit classical signaling, that is restricted to cell membranes, as well as newly described persistent signaling that depends on internalization of the GPCR bound to β-arrestins. Termination of non-canonical endosomal signaling requires intraluminal acidification and sophisticated protein trafficking machineries. The GPCR cycle, described in more detail below, is an elegant cellular solution for sensing a specific exogenous signal, transducing it to a signaling cascade, and then terminating the signal. GPCRs are widely represented in most life forms, from bacteria to fungi and animals, including all of the major model organisms.

GPCRs comprise a single polypeptide that is folded into a spherical shape and retained in the plasma membrane. They are activated through extracellular signals in the form of mediators or ligands.

G protein-coupled receptors (GPCRs) are classically defined as the receptor, G-protein and downstream effectors, the alpha subunit of the G-protein being the primary signaling molecule. However, it has become clear that this greatly oversimplifies the complexities of GPCR signaling (Gurevich & Gurevich 2008). All known GPCRs share a common architecture of seven membrane-spanning helices connected by intra- and extracellular loops.

Classically, G-protein-coupled receptors (GPCRs) are thought to activate G protein from the plasma membrane and are subsequently desensitized by β-arrestin (β-arr).
