GPCR Binding and JNK3 Activation by Arrestin-3 Have Different Structural Requirements
Arrestins bind active phosphorylated G protein-coupled receptors (GPCRs). Among the four mammalian subtypes, only arrestin-3 facilitates the activation of JNK3 in cells.

The Role of ICL1 and H8 in Class B1 GPCRs; Implications for Receptor Activation
The first intracellular loop (ICL1) of G protein-coupled receptors (GPCRs) has received little attention, although there is evidence that, with the 8th helix (H8), it is involved in early conformational changes following receptor activation as well as ...

Arrestins: Introducing Signaling Bias Into Multifunctional Proteins. [PDF]
Arrestins were discovered as proteins that bind active phosphorylated G protein-coupled receptors (GPCRs) and block their interactions with G proteins, i.e., for their role in homologous desensitization of GPCRs. Mammals express only four arrestin subtypes, two of which are largely restricted to the retina.

Differential Signaling Profiles of MC4R Mutations with Three Different Ligands [PDF]
The melanocortin 4 receptor (MC4R) is a key player in hypothalamic weight regulation and energy expenditure as part of the leptin-melanocortin pathway. Mutations in this G protein coupled receptor (GPCR) are the most common cause for monogenetic obesity,

Signaling bias is the ability of a receptor to differentially activate downstream signaling pathways in response to different ligands. Bias investigations have been hindered by inconsistent results in different cellular contexts.

Signal Evolution: ‘Shaky’ Evidence for Sensory Bias [PDF]
A study of tropical crickets suggests that a twitchy response to ultrasonic bat calls has been co-opted for mate location. The neuroethological approach picks apart some surprising evolutionary steps that could inform the widespread occurrence of complex duetting behaviour.

Neural Signals for the Detection of Unintentional Race Bias [PDF]
We examined the hypothesis that unintentional race-biased responses may occur despite the activation of neural systems that detect the need for control. Participants completed a sequential priming task that induced race-biased responses on certain trials while electroencephalography was recorded. The error-related negativity (ERN) wave, a component of

Computationally designed GPCR quaternary structures bias signaling pathway activation
Computational modeling and design of G Protein-Coupled Receptor quaternary structures reveals a signaling bias switch at the receptor dimer interface that selectively controls G protein vs β-arrestin activation.

Parmodulins Inhibit Thrombus Formation Without Inducing Endothelial Injury Caused by Vorapaxar [PDF]
Protease-activated receptor-1 (PAR1) couples the coagulation cascade to platelet activation during myocardial infarction and to endothelial inflammation during sepsis. This receptor demonstrates marked signaling bias.
