Dvl1 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
DVL1 (Dishevelled Segment Polarity Protein 1) is a key intracellular scaffold protein in the Wnt signaling pathway. DVL1 transduces extracellular Wnt signals from Frizzled receptors to downstream effectors, including β-catenin stabilization. DVL1 localizes to synapses and regulates synaptic formation, function, and plasticity. Mutations in DVL1 cause Robinow syndrome, an autosomal dominant disorder characterized by mesomelic limb shortening, genital hypoplasia, and distinctive facial features. DVL1 dysfunction has been implicated in Alzheimer's disease and autism spectrum disorders. [1]
