Insights

G protein-coupled receptors (GPCRs) use membrane trafficking to control signaling location and cellular responses. This review explores how receptor trafficking regulates GPCRs in reproduction and pregnancy for therapeutic potential.

Area of Science:

  • Endocrinology
  • Cell Biology
  • Pharmacology

Background:

  • G protein-coupled receptors (GPCRs) mediate diverse physiological functions through complex signaling pathways.
  • GPCRs crucial for reproduction and pregnancy face dynamic extracellular environments.
  • Understanding how GPCRs achieve functional pleiotropy in cellular responses is critical.

Purpose of the Study:

  • To review the role of membrane trafficking in regulating GPCR signaling location.
  • To explore spatial control of GPCRs within the endomembrane system and plasma membrane.
  • To discuss the relevance of these mechanisms in physiological and pathophysiological conditions.

Main Methods:

  • Review of current literature on GPCRs, membrane trafficking, and signaling.
  • Analysis of mechanisms controlling GPCR location via endocytic and exocytic pathways.
  • Examination of evidence for spatial regulation within the endomembrane system.

Main Results:

  • Membrane trafficking is central to regulating GPCR signal location and downstream responses.
  • GPCRs are organized within plasma membrane microdomains, influenced by trafficking pathways.
  • Spatial control of GPCRs extends to the endomembrane system, impacting signaling.

Conclusions:

  • Membrane trafficking provides a key mechanism for functional pleiotropy in GPCR signaling.
  • Understanding GPCR trafficking is crucial for comprehending reproductive and pregnancy physiology.
  • Targeting GPCR trafficking offers potential for developing novel therapeutic strategies.

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...

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.

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,...

Activation and Inactivation of G Proteins01:22

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...
