Abstract:
CNS angiogenesis and blood-brain barrier integrity are controlled by the canonical Wnt pathway. In this issue of Neuron, Cho et al. (2017) use advanced mouse genetics and biochemical experiments to unravel the ligand-specific association of membrane proteins GPR124 and RECK with Wnt receptor complexes.
Insights
The Wnt pathway regulates brain blood vessel growth and integrity. Researchers discovered how GPR124 and RECK proteins specifically bind to Wnt receptors, clarifying pathway control.
Area of Science:
- Neuroscience
- Molecular Biology
- Cell Biology
Background:
- The canonical Wnt pathway is crucial for central nervous system (CNS) angiogenesis.
- Maintaining blood-brain barrier (BBB) integrity is vital for CNS function.
- Understanding the molecular mechanisms controlling these processes is essential.
Purpose of the Study:
- To investigate the ligand-specific interactions of membrane proteins GPR124 and RECK with Wnt receptor complexes.
- To elucidate the role of these interactions in CNS angiogenesis and BBB integrity.
Main Methods:
- Advanced mouse genetics to study protein function in vivo.
- Biochemical experiments to analyze protein-protein interactions.
- Analysis of Wnt signaling components and their association with GPR124 and RECK.
Main Results:
- Demonstrated specific associations between GPR124 and RECK with distinct Wnt receptor complexes.
- Provided evidence for the role of these specific interactions in regulating CNS angiogenesis.
- Showcased the importance of these membrane proteins in maintaining blood-brain barrier integrity.
Conclusions:
- GPR124 and RECK play critical, ligand-specific roles in modulating Wnt signaling.

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

4.5K
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

18.1K
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...

4.3K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

5.0K
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.

10.8K
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
