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,

The Endothelial CXCR Family in Vascular Health and Disease
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

Pepducin-mediated cardioprotection via β-arrestin-biased β2-adrenergic receptor-specific signaling [PDF]
Reperfusion as a therapeutic intervention for acute myocardial infarction-induced cardiac injury itself induces further cardiomyocyte death. β-arrestin (βarr)-biased β-adrenergic receptor (βAR) activation promotes survival signaling responses in vitro ...

Identification of chemokine receptors as potential modulators of endocrine resistance in oestrogen receptor–positive breast cancers [PDF]
Introduction Endocrine therapies target oestrogenic stimulation of breast cancer (BC) growth, but resistance remains problematic. Our aims in this study were (1) to identify genes most strongly associated with resistance to endocrine therapy by ...

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

β-Arrestins and Cell Signaling [PDF]
Upon their discovery, β-arrestins 1 and 2 were named for their capacity to sterically hinder the G protein coupling of agonist-activated seven-transmembrane receptors, ultimately resulting in receptor desensitization. Surprisingly, recent evidence shows that β-arrestins can also function to activate signaling cascades independently of G protein ...

Structural basis of arrestin-3 activation and signaling
While arrestins are mainly associated with GPCR signaling, arrestin-3 can signal independently of receptor interaction. Here the authors present the structure of arrestin-3 bound to inositol hexakisphosphate (IP6) and propose a model for arrestin-3 ...

Structural studies of phosphorylation-dependent interactions between the V2R receptor and arrestin-2
The interaction between a GPCR, such as the vasopressin receptor-2 (V2R), and arrestin depends on the receptors’ phosphorylation pattern. Here authors use FRET and NMR to analyze the phosphorylation patterns of the V2R-arrestin complex and show that ...

Targeting protein–protein interactions within the cyclic AMP signaling system as a therapeutic strategy for cardiovascular disease [PDF]
The cAMP signaling system can trigger precise physiological cellular responses that depend on the fidelity of many protein–protein interactions, which act to bring together signaling intermediates at defined locations within cells.

Abstract Purpose To assess in Royal College of Surgeons (RCS) rats if the combination of two previously documented neuroprotective strategies: minocycline administration and bone marrow–derived mononuclear cells (BM‐MNCs) intravitreal transplantation, offers enhanced neuroprotection compared with each treatment alone.
