DVL3 (Dishevelled Segment Polarity Protein 3) is a key component of the Wnt/β-catenin signaling pathway, involved in neuronal development, synaptic plasticity, and axonal guidance. The DVL3 gene encodes a cytoplasmic protein with DIX, PDZ, and DEP domains that mediate protein-protein interactions critical for Wnt signal transduction.
DVL3 encodes another member of the Dishevelled protein family with functions similar to DVL1 and DVL2. DVL3 is involved in Wnt/β-catenin signaling, planar cell polarity (PCP) pathway, and regulation of microtubule dynamics. It plays essential roles in neuronal migration, axon guidance, and synaptic formation.
In the nervous system, DVL3 regulates dendritic arborization, synapse formation, and neural circuit assembly. It interacts with various proteins involved in synaptic transmission and plasticity.
Expressed in the brain during development and in adulthood. Highest expression in the cortex, hippocampus, and thalamus.
| Disease | Variants | Inheritance | Mechanism |
