Nuclear β-arrestin1 is a critical cofactor of hypoxia-inducible factor-1α signaling in endothelin-1-induced ovarian tumor progression [PDF]
Hypoxia-inducible factor-1α (HIF-1α) mediates the response to hypoxia or other stimuli, such as growth factors, including endothelin-1 (ET-1), to promote malignant progression in numerous tumors.

Comprehensive transduceromic profiling of NOP receptor ligands at different Gα subunits
Abstract Background and Purpose The nociceptin/orphanin FQ (N/OFQ) peptide receptor (NOP) is an opioid receptor family member with distinct pharmacology and broad therapeutic potential. NOP receptors regulate functions such as nociception, stress reactivity, reward, mood, autonomic tone, immunity and sleep/wake cycle.

Lock, relax, load, and shoot: a molecular perspective on Nedd4 regulation
Structural basis of inactive and active states of the Nedd4 HECT E3 ligase subfamily, following a ‘lock, relax, load, and shoot’ mechanism. In the locked, autoinhibited state, intramolecular domain interactions restrain the HECT domain. Relaxation releases these restraints, allowing loading of ubiquitin onto the catalytic cysteine, followed by the ...

PAR1 Agonists Stimulate APC-Like Endothelial Cytoprotection and Confer Resistance to Thromboinflammatory Injury [PDF]
Stimulation of protease-activated receptor 1 (PAR1) on endothelium by activated protein C (APC) is protective in several animal models of disease, and APC has been used clinically in severe sepsis and wound healing.

Spatiotemporal dynamics of β‐arrestin‐mediated Src activation in 5‐HT7 receptor signaling pathway
GPCRs induce distinct cellular responses via G protein‐ or β‐arrestin‐mediated signaling pathways. This study revealed that β‐arrestin‐biased 5‐HT7R ligand induces slow, sustained Src activation, contrasting with transient G protein‐mediated activation.

Structural Determinants of Arrestin Functions [PDF]
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 ...

Behavioral Characterization of β-Arrestin 1 Knockout Mice in Anxiety-Like and Alcohol Behaviors
β-Arrestin 1 and 2 are highly expressed proteins involved in the desensitization of G protein-coupled receptor signaling which also regulate a variety of intracellular signaling pathways.

Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

Arrestins in Host–Pathogen Interactions
In the context of host-pathogen interaction, host cell receptors and signaling pathways are essential for both invading pathogens, which exploit them for their own profit, and the defending organism, which activates early mechanism of defense, known as innate immunity, to block the aggression.
