Molecular basis of anaphylatoxin binding, activation, and signaling bias at complement receptors [PDF]
Summary The complement system is a critical part of our innate immune response, and the terminal products of this cascade, anaphylatoxins C3a and C5a, exert their physiological and pathophysiological responses primarily via two GPCRs, C3aR and C5aR1 ...

Resonating with the signaling bias of CXCR7. [PDF]
Kleist et al. combine NMR spectroscopy and residue contact network analysis to identify a potential allosteric network in CXCR7, a β-arrestin-biased chemokine receptor, which links the extracellular ligand-binding pocket and the intracellular transducer-coupling region through the receptor transmembrane core.

Structural Insights into M1 Muscarinic Acetylcholine Receptor Signaling Bias between Gαq and β-Arrestin through BRET Assays and Molecular Docking [PDF]
The selectivity of drugs for G protein-coupled receptor (GPCR) signaling pathways is crucial for their therapeutic efficacy. Different agonists can cause receptors to recruit effector proteins at varying levels, thus inducing different signaling ...

Human Gain-of-Function MC4R Variants Show Signaling Bias and Protect against Obesity [PDF]
Summary The melanocortin 4 receptor (MC4R) is a G protein-coupled receptor whose disruption causes obesity. We functionally characterized 61 MC4R variants identified in 0.5 million people from UK Biobank and examined their associations with body mass ...

Ligand bias in receptor tyrosine kinase signaling [PDF]
Ligand bias is the ability of ligands to differentially activate certain receptor signaling responses compared with others. It reflects differences in the responses of a receptor to specific ligands and has implications for the development of highly specific therapeutics.

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.

G Protein and β-Arrestin Signaling Bias at the Ghrelin Receptor [PDF]
Background: The G protein coupled receptor GHSR1a mediates feeding and addictive behaviors. Results: Mutagenesis of the second intracellular loop of GHSR1a generates biased receptors, favoring distinct signaling events. Conclusion: Receptor conformations

Temporal Bias: Time-Encoded Dynamic GPCR Signaling [PDF]
Evidence suggests that cells can time-encode signals for secure transport and perception of information, and it appears that this dynamic signaling is a common principle of nature to code information in time. G-protein-coupled receptor (GPCR) signaling networks are no exception as their composition and signal transduction appear temporally flexible. In
