Rules and mechanisms governing G protein coupling selectivity of GPCRs
Summary: G protein-coupled receptors (GPCRs) convert extracellular stimuli into intracellular signaling by coupling to heterotrimeric G proteins of four classes: Gi/o, Gq, Gs, and G12/13.

Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]
Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

Stabilization of G protein-coupled receptors by point mutations
G protein-coupled receptors (GPCRs) are flexible integral membrane proteins involved in transmembrane signaling. Their involvement in many physiological processes makes them interesting targets for drug development.

Frizzled Proteins are bona fide G Protein-Coupled Receptors [PDF]
Receptors of the Frizzled family initiate Wnt ligand-dependent signaling controlling multiple steps in organism development and highly conserved in evolution. Misactivation of the Wnt/Frizzled signaling is cancerogenic.

The role of dimerisation in the cellular trafficking of G-protein-coupled receptors [PDF]
The concept that G-protein-coupled receptors can exist as homomeric and/or heteromeric complexes is now well established. Despite this, how dynamic such interactions are and if this may be modulated during receptor trafficking remain topics of debate ...

Methods for Studying Endocytotic Pathways of Herpesvirus Encoded G Protein-Coupled Receptors
Endocytosis is a fundamental process involved in trafficking of various extracellular and transmembrane molecules from the cell surface to its interior. This enables cells to communicate and respond to external environments, maintain cellular homeostasis,

Crystallization of G Protein-Coupled Receptors [PDF]
Oligomerization is one of several mechanisms that can regulate the activity of G protein-coupled receptors (GPCRs), but little is known about the structure of GPCR oligomers. Crystallography and NMR are the only methods able to reveal the details of receptor-receptor interactions at an atomic level, and several GPCR homodimers already have been ...

Pepducins as a potential treatment strategy for asthma and COPD. [PDF]
Current therapies to treat asthma and other airway diseases primarily include anti-inflammatory agents and bronchodilators. Anti-inflammatory agents target trafficking and resident immunocytes and structural cells, while bronchodilators act to prevent or

Computational Modeling for the Activation Cycle of G-proteins by G-protein-coupled Receptors
In this paper, we survey five different computational modeling methods. For comparison, we use the activation cycle of G-proteins that regulate cellular signaling events downstream of G-protein-coupled receptors (GPCRs) as a driving example.
