VGLL3 binds TEAD1, TEAD3, and TEAD4 in myoblasts and/or myotubes, as determined by interaction proteomics. Unlike YAP/TAZ, VGLL3 showed no interaction with proteins of the Hippo kinase cascade. Vgll3 overexpression reduced Hippo negative-feedback loop activity, promoted myogenic differentiation, and mainly repressed gene expression including Myf5, Pitx2, Pitx3, and certain Wnt and IGFBP genes. siRNA-mediated Vgll3 knockdown suppressed myoblast proliferation. |

VGLL3 (together with TEADs) promotes cancer cell proliferation by activating the Hippo pathway: VGLL3 expression induces transcription of LATS2 and AMOTL2, leading to YAP/TAZ inactivation. VGLL3 knockdown increased nuclear localization of YAP and TAZ, and knockdown of LATS2 or AMOTL2 repressed breast tumor cell proliferation. |

VGLL3 is specifically expressed in myofibroblasts in fibrotic hearts and promotes collagen production. Substrate stiffness triggers VGLL3 nuclear translocation via the integrin β1-Rho-actin pathway. In the nucleus, VGLL3 undergoes liquid-liquid phase separation via its low-complexity domain, is incorporated into non-paraspeckle NONO condensates containing EWSR1, binds EWSR1, and suppresses miR-29b (which targets collagen mRNA). Vgll3-deficient mice showed significantly attenuated cardiac fibrosis after myocardial infarction, with increased miR-29b expression. |

VGLL3 acts as a transcription cofactor with female-biased expression that regulates a genome-wide network of genes strongly associated with multiple autoimmune diseases (lupus, scleroderma, Sjögren's syndrome). The VGLL3-regulated gene network overlaps with inflammatory processes in cutaneous lupus and is independent of biological age and sex-hormone regulation. |

Skin-directed overexpression of murine VGLL3 is sufficient to drive cutaneous and systemic autoimmune disease resembling SLE, including B cell expansion, autoantibody production, immune complex deposition, and end-organ damage. Excess epidermal VGLL3 drives a proinflammatory gene expression program including upregulation of BAFF, IFN-κ, and CXCL13. |

VGLL3 promotes expression and secretion of IL-1α, likely through its association with TEADs, which activates NF-κB. TGF-β signaling induces VGLL3 (via Smad3 and Smad4), and VGLL3 is required for TGF-β-induced IL-1α secretion and NF-κB activation. VGLL3-dependent IL-1α secretion contributes to constitutive NF-κB activation in highly malignant breast cancer cells. |

VGLL3 is a cofactor for TEAD family transcription factors and is amplified in ~10% of soft tissue sarcomas (chromosome 3p12 amplicon). Inhibition of VGLL3 in cell lines with amplification/overexpression leads to decreased proliferation rate and, to a lesser extent, decreased migration properties. |

VGLL3 promotes IRF3 activation and IFN-β1 expression in rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS), which then drives expression of IFN-stimulated genes in an autocrine manner. Mechanistically, VGLL3 inhibits WWTR1 (TAZ) expression and modulates AMOTL2, and these Hippo pathway molecules mediate VGLL3's regulation of IRF3 activation and IFN-β1 production. |

VGLL3 induces expression of GART (a trifunctional enzyme for de novo purine synthesis from glutamine), thereby increasing cancer cell dependency on de novo nucleotide synthesis. VGLL3 knockdown in breast cancer cells reduced GART expression, and GART inhibition or knockdown repressed proliferation of VGLL3-expressing cells, which was rescued by inosine monophosphate supplementation. |

VGLL3 plays a role in DNA damage response (DDR): it is recruited to DNA damage sites in a PARylation-dependent manner. VGLL3 depletion impairs accumulation of RNF8 and RAD51 at damage sites, reducing homologous recombination efficiency. Mechanistically, VGLL3 prevents CtIP from KLHL15-mediated ubiquitination and degradation via competitive binding with KLHL15, and stabilizes MDC1 by limiting TRIP12-MDC1 interaction while promoting USP7-MDC1 association, enabling optimal RNF8 signaling. VGLL3 depletion sensitizes tumor xenografts to etoposide. |

HERC6, an IFN-induced E3 ubiquitin ligase, negatively regulates STING-TBK1 signaling in a female-biased manner. HERC6 knockdown leads to enhanced ISG responses dependent on VGLL3, establishing that HERC6 acts through modulation of LATS2 and TBK1 activity upstream of VGLL3 to control female-biased type I IFN responses to dsDNA. |

VGLL3 is a transcriptional target of TAZ (WWTR1) and is required for TAZ-mediated repression of adipogenic enhancers. TAZ represses PPARγ-bound target enhancers (reducing H3K27ac occupancy) in a TEAD-dependent manner, and Vgll3 is a key downstream effector mediating this repression of adipocyte differentiation. |

A structure-function analysis of VGLL1, VGLL2, and VGLL3 TEAD-binding domains across >2400 vertebrate sequences reveals that VGLL3 binds TEAD via a conserved Tondu motif. The analysis identifies that one vertebrate VGLL paralog with both a Tondu motif and an Ω-loop (present in arthropod Vg and YAP) is conserved, suggesting selective pressure to maintain this structural feature. VGLL2 and VGLL3 variants with altered TEAD-binding domains in mammals may have distinct biological functions. |

VGLL3 regulates DAPK2-mediated autophagy to promote osteoblast differentiation. Vgll3 knockdown in MC3T3-E1 cells suppressed autophagic flux (fewer autophagic vacuoles, decreased LC3-II, increased p62). DAPK2 was identified as a downstream effector of VGLL3; Dapk2 knockdown phenocopied Vgll3 knockdown. DAPK2 overexpression partially rescued autophagic activity and osteogenic differentiation in Vgll3-deficient cells. Rapamycin partially restored autophagy and differentiation in Vgll3-deficient cells. FOXM1 was implicated as a potential transcriptional regulator of DAPK2. |
