August 2022 "Histamine exerts its physiological functions through its four receptor subtypes. In this work, we report the subcellular localization of histamine receptor 2 (H2R), a G protein-coupled receptor (GPCR), which is expressed in a wide variety of cell and tissue types. Using fluorescently tagged histamine, we explored H2R-histamine binding interaction, which exhibits a

The clinical success of GLP-1 and GIP receptor agonists has pushed the field toward additional pathways No gene encodes a dedicated amylin receptor. The functional receptor assembles only when the calcitonin receptor (CALCR), a class B GPCR, associates with one of three receptor activity-modifying proteins, or RAMPs. CALCR partnered with RAMP1, RAMP2, or RAMP3 produces three distinct amylin receptors: AMY1, AMY2, and

Biased signaling frameworks centered on receptor conformations have a structural limitation when selectivity is also encoded at the level of receptor–transducer complex assembly. The degree to which intracellular interfaces contribute to coupling specificity varies across receptors The consequences for coupling specificity differ across receptor systems. P2Y14, activated by UDP-sugars as a DAMP receptor, is targeted through antagonism.

Eleonora Comeo synthesizes fluorescent ligands to watch adenosine receptor pharmacology happen in living cells - and explains why targeting these receptors keeps failing. << Back to podcast list Strategic One reason is that selectivity in this family is not just a matter of receptor subtype. in another tissue, because the receptor is already doing something important there. transfected receptor signal from endogenous background.
