CKI epsilon (casein kinase I epsilon) phosphorylates Dvl-1 and enhances its binding to Frat-1; the amino acid region 228–250 of Dvl-1 is necessary for binding Frat-1. This complex is required for Wnt-3a-induced accumulation of beta-catenin and activation of TCF-4-dependent transcription. |

DVL1 promotes hyperphosphorylation of Frizzled3 and prevents its internalization, thereby inhibiting planar cell polarity (PCP) signaling in commissural axon growth cones. Vangl2 antagonizes this by reducing Frizzled3 phosphorylation and promoting its internalization, sharpening PCP signaling at filopodia tips for directional Wnt sensing. |

EPS8 (a substrate of activated EGF receptor) physically interacts with the PDZ domain of Dvl1. In the presence of EPS8, Dvl1 becomes hyperphosphorylated; conversely, Dvl1 inhibits EGF receptor-induced tyrosine phosphorylation of EPS8. |

The DIX domain of DVL1 physically interacts with the DIX domain of Axin1 to form a stable complex; co-expression of both DIX domains in a multi-cistronic system stabilizes the otherwise unstable individual DIX domain fragments, enabling complex formation confirmed by affinity chromatography and size-exclusion chromatography. |

Wnt5a signals specifically through DVL1 to repress ribosomal DNA (rDNA) transcription by RNA polymerase I in breast cancer cells. DVL1 accumulates in nucleolar organizer regions (NORs) and binds rDNA chromatin; upon DVL1 binding, the Pol I transcription activator SIRT7 is released from rDNA loci coincident with disassembly of Pol I transcription machinery at the rDNA promoter. |

De novo heterozygous frameshift mutations in DVL1 exon 14 (penultimate exon) cause autosomal-dominant Robinow syndrome. Mutant transcripts escape nonsense-mediated decay and are predicted to generate C-terminally truncated proteins with a distinct -1 reading-frame terminus, implicating loss/alteration of the DVL1 C-terminal domain in non-canonical Wnt-5a pathway disruption. |

De novo DVL1 frameshift mutations that delete the C-terminus and replace it with a novel highly basic sequence cause Robinow syndrome with osteosclerosis (RS-OS). In vitro TOPFlash assays showed the mutant allele alone was less active than wild-type in canonical Wnt signaling, but co-expression of mutant and wild-type alleles produced ~2-fold higher canonical Wnt activity than wild-type alone, suggesting a dominant gain-of-function interaction that may underlie the osteosclerotic phenotype. |

DVL1 interacts with somatostatin receptor 2 (Sstr2) in a ligand-independent manner and targets Sstr2 for lysosomal degradation. This interaction does not affect receptor internalization, recycling, or adenylyl cyclase signaling but suppresses agonist-stimulated ERK1/2 activation. Wnt overexpression potentiates DVL1-dependent Sstr2 degradation, and Wnt pathway inhibitors boost Sstr2 expression in neuroendocrine tumor cells. |

Dvl1 has a dual epithelial and immune cell function required for normal gut homeostasis. Dvl1-/- mice show increased gut transit time, mislocalization of Paneth cells, and increased CD8+ T cells. Bone marrow chimera experiments established that GI dysfunction requires abnormalities in both epithelial and immune compartments. Gut microbiota manipulation rescued transit abnormality without correcting cellular defects. |

DACT3 directly interacts with DVL1 (confirmed by co-immunoprecipitation) and inhibits DVL1-induced activation of canonical Wnt signaling. The DACT3–DVL1 interaction inhibits phosphorylation of GSK-3β at serine 9 and β-catenin at serine 675, thereby reducing β-catenin nuclear translocation and downstream transcription. DACT3 suppresses DVL1-driven invasion, proliferation, migration, and cisplatin resistance in NSCLC cells. |
