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.
- 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
- Wnt signal transduction: Central mediator of canonical and non-canonical Wnt signaling
- Canonical pathway: Inhibits β-catenin destruction complex, leading to β-catenin stabilization
- Non-canonical pathways: Mediates planar cell polarity (PCP) and Wnt/Ca²⁺ signaling
- Neuronal functions:
- Dendrite morphogenesis
- Synapse formation and function
- Axon guidance
- Neurogenesis
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
- Wnt signaling modulators for neurodegenerative diseases
- Small molecules targeting DVL1 protein interactions
- Gene therapy approaches
