AI Article Synopsis

  • Adhesion G protein-coupled receptors (aGPCRs) are a unique subgroup of the GPCR superfamily characterized by large, multi-domain N termini and the ability to undergo autoproteolytic cleavage.
  • Despite the established role of GPCRs in pharmacology, no therapies targeting the 33 aGPCR members have been approved or are in clinical trials, although their link to various diseases is becoming clearer.
  • The discussion highlights the potential for drug discovery in aGPCRs, focusing on challenges like target identification and validation, and outlines a framework for developing modulators, exemplified by ADGRG1.

Article Abstract

Adhesion G protein-coupled receptors (aGPCRs) - one of the five main families in the GPCR superfamily - have several atypical characteristics, including large, multi-domain N termini and a highly conserved region that can be autoproteolytically cleaved. Although GPCRs overall have well-established pharmacological tractability, currently no therapies that target any of the 33 members of the aGPCR family are either approved or in clinical trials. However, human genetics and preclinical research have strengthened the links between aGPCRs and disease in recent years. This, together with a greater understanding of their functional complexity, has led to growing interest in aGPCRs as drug targets. A framework for prioritizing aGPCR targets and supporting approaches to develop aGPCR modulators could therefore be valuable in harnessing the untapped therapeutic potential of this family. With this in mind, here we discuss the unique opportunities and challenges for drug discovery in modulating aGPCR functions, including target identification, target validation, assay development and safety considerations, using ADGRG1 as an illustrative example.

In thrombosis and hemostasis, the formation of a platelet-fibrin thrombus or clot is a highly controlled process that varies, depending on the pathological context. Major signaling pathways in platelets are well established. However, studies with genetically modified mice have identified the contribution of hundreds of additional platelet-expressed proteins in arterial thrombus formation and bleeding.

An Alternative Mode of GPCR Transactivation: Activation of GPCRs by Adhesion GPCRs.

Int J Mol Sci

G protein-coupled receptors (GPCRs), critical for cellular communication and signaling, represent the largest cell surface protein family and play important roles in numerous pathophysiological processes. Consequently, GPCRs have become a primary focus in drug discovery efforts. Beyond their traditional G protein-dependent signaling pathways, GPCRs are also capable of activating alternative signaling mechanisms, including G protein-independent signaling, biased signaling, and signaling crosstalk.

SOX9 is a crucial transcriptional regulator of cartilage development and homeostasis. Dysregulation of is associated with a wide spectrum of skeletal disorders, including campomelic dysplasia, acampomelic campomelic dysplasia, and scoliosis. Yet how variants contribute to the spectrum of axial skeletal disorders is not well understood.

G-protein coupled receptor GPR124 protects against podocyte senescence and injury in diabetic kidney disease.

Although emerging studies highlight the pivotal role of podocyte senescence in the pathogenesis of diabetic kidney disease (DKD) and aging-related kidney diseases, therapeutic strategies for preventing podocyte senescence are still lacking. Here, we identified a previously unrecognized role of GPR124, a novel adhesion G protein-coupled receptor, in maintaining podocyte structure and function by regulation of cellular senescence in DKD. Podocyte GPR124 was significantly reduced in db/db diabetic (a type 2 diabetic mouse model) and streptozocin-induced diabetic mice (a type 1 diabetic model), which was further confirmed in kidney biopsies from patients with DKD.

Occurrence of degenerative interactions is thought to serve as a mechanism underlying hybrid unfitness in most animal systems. However, the molecular mechanisms underpinning the genetic interaction and how they contribute to overall hybrid incompatibilities are limited to only a handful of examples. A vertebrate model organism, Xiphophorus, is used to study hybrid dysfunction, and it has been shown from this model that diseases, such as melanoma, can occur in certain interspecies hybrids.
