Abstract Background and Purpose Positive allosteric modulators (PAMs) engage sites distinct from the orthosteric CB1 cannabinoid receptor binding site. GAT211, a racemic ligand, contains GAT228 (R) and GAT229 (S) enantiomers. Whether enantiomer‐mediated differences in allosteric activation or positive allosteric modulation translate into differences in

Arrestin interactions with the μ-opioid receptor
Upon agonist binding the u-opioid receptor (MOPr) is phosphorylated and can recruit arrestin-2 (beta-arrestin-l) and arrestin-3 (p-arrestin-2). Apart from promoting the desensitization and intemalization of the MOPr, the binding of arrestins can also ...

Abstract Clinically non‐functioning pituitary neuroendocrine tumors (NF‐PitNETs) lack effective medical therapies, and the role of somatostatin receptor ligands (SRLs) and dopamine agonists (DAs) in this setting is controversial. We evaluated the in vitro response of NF‐PitNETs to multiple SRL and/or DA treatments, focusing on the role of receptor ...

Annexin A4 (A4) inhibits adenylyl cyclase 5 and may protect the heart during chronic β‐adrenergic stress. After 7 days of isoprenaline, A4‐deficient mice showed greater cardiomyocyte hypertrophy, prolonged action potentials, reduced Ito, preserved ICaL with altered activation, increased NCX1, and enhanced acute cAMP responsiveness compared with wild ...

β‑Arrestin‑2 BRET Biosensors Detect Different β‑Arrestin‑2 Conformations in Interaction with GPCRs
β-Arrestins are critical regulators of G protein-coupled receptors (GPCRs) that desensitize G protein signaling, promote receptor internalization, and initiate signaling on their own.

Structure and Self-Association of Arrestin-1
Arrestins halt cell signaling by binding to phosphorylated activated G protein-coupled receptors. Arrestin-1 binds to rhodopsin, arrestin-4 binds to cone opsins, and arrestins-2,3 bind to the rest of GPCRs. In addition, it has been reported that arrestin-

G protein-coupled receptors (GPCRs), the key regulators of cellular signaling, transduce signals through G proteins or arrestins. G protein- or arrestin-mediated signal transduction induces distinct functional consequences, and therefore the molecular ...
