Function and dynamics of the intrinsically disordered carboxyl terminus of β2 adrenergic receptor
Nature Communications, 2023 Advances in structural biology have provided important mechanistic insights into signaling by the transmembrane core of G-protein coupled receptors (GPCRs); however, much less is known about intrinsically disordered regions such as the carboxyl terminus (

Sodium Ions Affect GPR17 Conformational States and Functionality
Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Sodium is an allosteric modulator of several class‐A GPCR regulating active versus inactive conformation state and may be a critical issue for the optimization of crystallization procedures. Herein, the role of Na+ in the regulation of GPR17 conformational states was studied through MD simulations of GPR17 wild‐type and mutated on two ...

β-Arrestins in the Immune System [PDF]
, 2013 β-Arrestins regulate G protein-coupled receptors through receptor desensitization while also acting as signaling scaffolds to facilitate numerous effector pathways. Recent studies have provided evidence that β-arrestins play a key role in inflammatory responses.

Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis
Andrology, EarlyView.ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.

β-Arrestin-Mediated Signaling Improves the Efficacy of Therapeutics
Journal of Pharmacological Sciences, 2012 β-Arrestins (β-arrestin-1 and β-arrestin-2) were first identified as proteins that have the ability to desensitize G protein-coupled receptors (GPCRs). However, it has recently been found that β-arrestins can activate signaling pathways independent of G ...

Compartmentalisation in cAMP signalling: A phase separation perspective
British Journal of Pharmacology, EarlyView.Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

GPCR Signaling Regulation: The Role of GRKs and Arrestins
Frontiers in Pharmacology, 2019 Every animal species expresses hundreds of different G protein-coupled receptors (GPCRs) that respond to a wide variety of external stimuli. GPCRs-driven signaling pathways are involved in pretty much every physiological function and in many pathologies.

Structural Determinants of Arrestin Functions [PDF]
, 2013 Arrestins are a small protein family with only four members in mammals. Arrestins demonstrate an amazing versatility, interacting with hundreds of different G protein-coupled receptor (GPCR) subtypes, numerous nonreceptor signaling proteins, and components of the internalization machinery, as well as cytoskeletal elements, including regular ...
