Dishevelled 1 (DVL1) is a key scaffolding protein in the Wnt signaling pathway. It is a cytoplasmic protein that transduces Wnt signals from Frizzled receptors to downstream effectors, playing essential roles in development and neuronal function.

Structure

• Size: 670 amino acids (canonical isoform)

• Molecular weight: ~70-80 kDa

• Domains:

  • DAX domain (N-terminal): Mediates dimerization and interactions

  • PDZ domain: Protein-protein interactions

  • DEP domain (C-terminal): Membrane targeting and signal transduction

• Isoforms: Multiple isoforms due to alternative splicing

Function

1. Wnt signal transduction: Central mediator of canonical and non-canonical Wnt signaling

2. Canonical pathway: Inhibits β-catenin destruction complex, leading to β-catenin stabilization

3. Non-canonical pathways: Mediates planar cell polarity (PCP) and Wnt/Ca²⁺ signaling

4. Neuronal functions:

   • Dendrite morphogenesis

   • Synapse formation and function

   • Axon guidance

   • Neurogenesis

Role in Neurodegeneration

Alzheimer’s Disease:

• Impaired Wnt/DVL signaling in AD brains

• DVL1 regulates amyloid-beta generation

• Interacts with tau phosphorylation pathways

Parkinson’s Disease:

• Essential for dopaminergic neuron development

• DVL1 signaling may be protective in PD

Neurodevelopmental Disorders:

• DVL1 mutations cause autism and intellectual disability

• Affects synaptic function and neural circuit formation

Therapeutic Targeting

• Wnt signaling modulators for neurodegenerative diseases

• Small molecules targeting DVL1 protein interactions

• Gene therapy approaches
