Overview

FZD2 (Frizzled Class Receptor 2) is a seven-transmembrane receptor that binds Wnt ligands and activates both canonical (beta-catenin-dependent) and non-canonical (beta-catenin-independent) Wnt signaling pathways. It plays essential roles in embryonic neural development, neuronal differentiation, synapse formation, and adult brain function. FZD2 is expressed throughout the developing and adult nervous system.

Function

Wnt Receptor Signaling

FZD2 functions as a primary receptor for multiple Wnt proteins:

• Activates canonical Wnt/β-catenin pathway
• Triggers planar cell polarity (PCP) signaling
• Mediates Wnt/Ca²⁺ signaling
• Forms receptor complexes with LRP5/6 for canonical signaling

Neural Development

During development, FZD2 regulates:

• Neural tube formation and closure
• Neuronal progenitor proliferation
• Axon guidance and pathfinding
• Dendritic arborization
• Synapse formation

Adult Brain Function

In the adult brain, FZD2 modulates:

• Hippocampal synaptic plasticity and memory formation
• Cortical neuron survival
• Adult neurogenesis
• Cognitive function

Disease Associations

Alzheimer's Disease

FZD2 dysregulation contributes to AD pathogenesis:

• Altered Wnt signaling in AD brains
• FZD2-mediated neuroprotection against [Aβ](/proteins/amyloid-beta) toxicity
• Impaired synaptic plasticity via Wnt pathway disruption
• Therapeutic target potential

Neural Tube Defects

FZD2 mutations associated with:

• Spina bifida
• Anencephaly
• Craniorachischisis

Cancer

FZD2 overexpressed in various cancers:

• Breast cancer
• Gastric cancer
• Hepatocellular carcinoma

Expression

FZD2 is expressed in:

• Developing brain: Neural tube, ventricular zone
• [Hippocampus](/brain-regions/hippocampus): CA1-CA3 regions, dentate gyrus
• Cerebral [cortex](/brain-regions/cortex): All layers
• Cerebellum: Purkinje cells, granule cells
• Peripheral nervous system: Sensory ganglia

Interactions

FZD2 interacts with:

• WNT1, WNT3, WNT5A, WNT11: Wnt ligands
• LRP5, LRP6: Co-receptors
• DVL1, DVL2, DVL3: Dishevelled proteins
• AXIN1, AXIN2: Scaffold proteins
• GSK3β: Kinase

Therapeutic Targeting

FZD2-based approaches for neurodegeneration:

• FZD2 agonists to restore Wnt signaling
• Small molecule Wnt activators
• Antibody-based therapies
• Gene therapy for FZD2 expression
