Insights

Mutations in G protein-coupled receptors (GPCRs) and G proteins cause various human diseases. Understanding these genetic mutations is crucial for diagnosing and treating conditions like pseudohypoparathyroidism and McCune-Albright syndrome.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cellular Signaling

Background:

  • Heterotrimeric G proteins are key mediators of cellular responses to extracellular signals.
  • G protein-coupled receptors (GPCRs) form a large superfamily involved in signal transduction.
  • Dysregulation of G protein signaling is implicated in various physiological and pathological processes.

Purpose of the Study:

  • To review the role of mutations in GPCRs and G proteins in human diseases.
  • To highlight the link between genetic variations and disorders affecting multiple organ systems.
  • To provide an overview of G protein-coupled signal transduction.

Main Methods:

  • Literature review of genetic mutations in GPCRs and G proteins.
  • Analysis of clinical data associated with specific mutations.
  • Summary of signal transduction pathways involving G proteins.

Main Results:

  • Loss-of-function mutations in G protein alpha subunit genes cause pseudohypoparathyroidism.
  • Gain-of-function mutations lead to McCune-Albright syndrome.
  • Mutations in GPCRs and G proteins are increasingly recognized as causes of retinal, endocrine, metabolic, and developmental disorders.

Conclusions:

  • Mutations in GPCRs and G proteins are significant contributors to human disease.
  • Understanding these mutations is vital for disease diagnosis and therapeutic strategies.
  • GPCRs and G proteins represent important targets for pharmacological intervention.

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

G Protein-coupled Receptors

G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Activation and Inactivation of G Proteins

Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...

Transducer Mechanism: G Protein–Coupled Receptors

G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
GPCRs are also called heptahelical, 7TM, or...
