receptors (GPCRs), including the parathyroid hormone 1 receptor (PTH1R), a class B GPCR and an important modulator activation of PTH1R and its downstream signaling, we describe here that RAMP2 acts as a specific allosteric modulator Moreover, RAMP2 modulates PTH1R downstream signaling in an agonist-dependent manner, most notably increasing Employing homology modeling, we describe the putative structural molecular basis underlying our functional of RAMPs in the activation and signaling of a GPCR that may provide a new venue for highly specific modulation

We report that arrestin-3 modulates Fgr activity with a hallmark bell-shaped concentration-dependence interaction, we determined the crystal structure of the Fgr SH3 domain at 1.9 Å resolution and developed a model This model suggests that Fgr interacts with arrestin-3 at multiple sites and is consistent with the locations

October 2022 "Over three decades of research have provided thorough insights into G protein-coupled receptor (GPCR) regulation. In a recent issue of Molecular Cell, Fonseca et al. identified a previously overlooked desensitization mechanism. Agonist activation of the β2-adrenoceptor (β2AR) causes its S-nitrosylation that is required for the receptor to internalize and desensitize. Eliminating β2AR S-nitrosylation by mutation of C265 augments β2AR protein kinase A signaling, enables β2AR nitric oxide (NO) signaling, renders mice resistant to bronchoconstriction, and protects mice from allergen-induced asthma."

Therefore, the identification of such modulators as drug candidates is highly desirable. Currently, attention was mainly paid to biased signaling modulators targeting G protein-coupled receptors The biased signaling modulation of non-GPCR receptors has yet to be exploited. The challenges and methods for the discovery of TLR4 biased modulators are also outlined. modulators for other non-GPCR receptors.

August 2022 "The calcium-permeable cation channel TRPM3 can be activated by heat and the endogenous steroid pregnenolone sulfate. TRPM3's best understood function is its role as a peripheral noxious heat sensor in mice. However, the channel is expressed in various tissues and cell types including neurons as well as glial and epithelial cells. TRPM3 expression patterns differ between species and change during development. Furthermore, a plethora of TRPM3 variants that result from alternative splicing have been identified and the majority of these isoforms are yet to be characterized. Moreover, the mechanisms underlying regulation of TRPM3 are largely unexplored. In addition, a micro-RNA gene (miR-204) is located within the TRPM3 gene. This complexity makes it difficult to obtain a clear picture of TRPM3 characteristics. However, a clear picture is needed to unravel TRPM3's full potential as experimental tool, diagnostic marker and therapeutic target. Therefore, the newest data related to TRPM3 have to be discussed and to be put in context as soon as possible to be up-to-date and to accelerate the translation from bench to bedside. The aim of this review is to highlight recent results and developments with particular focus on findings from studies involving ocular tissues and cells or peripheral neurons of rodents and humans."

October 2022 ADGRL3 genomic variation implicated in neurogenesis and ADHD links functional effects to the incretin polypeptide GIP "Attention deficit/hyperactivity disorder (ADHD) is the most common childhood neurodevelopmental disorder. Single nucleotide polymorphisms (SNPs) in the Adhesion G Protein-Coupled Receptor L3 (ADGRL3) gene are associated with increased susceptibility to developing ADHD worldwide. However, the effect of ADGRL3 non-synonymous SNPs (nsSNPs) on the ADGRL3 protein function is vastly unknown. Using several bioinformatics tools to evaluate the impact of mutations, we found that nsSNPs rs35106420, rs61747658, and rs734644, previously reported to be associated and in linkage with ADHD in disparate populations from the world over, are predicted as pathogenic variants. Docking analysis of rs35106420, harbored in the ADGLR3-hormone receptor domain (HRM, a common extracellular domain of the secretin-like GPCRs family), showed that HRM interacts with the Glucose-dependent insulinotropic polypeptide (GIP), part of the incretin hormones family. GIP has been linked to the pathogenesis of diabetes mellitus, and our analyses suggest a potential link to ADHD. Overall, the comprehensive application of bioinformatics tools showed that functional mutations in the ADGLR3 gene disrupt the standard and wild ADGRL3 structure, most likely affecting its metabolic regulation. Further in vitro experiments are granted to evaluate these in silico predictions of the ADGRL3-GIP interaction and dissect the complexity underlying the development of ADHD."
