HFz6 acts as a negative regulator of canonical Wnt/β-catenin signaling by inhibiting TCF/LEF binding to target DNA without affecting β-catenin stabilization or nuclear TCF4 levels. HFz6 activates the TAK1-NLK pathway, which blocks TCF/LEF binding to target promoters, thereby inhibiting β-catenin-driven transcription. Both N- and C-terminal sequences of HFz6 are required for this repressive activity. |

FZD6 activates CaMKII-TAK1-NLK signaling, which attenuates canonical Wnt pathway activity while promoting STAT3 and NF-κB signaling, establishing FZD6 as a negative regulator of Wnt/β-catenin and a driver of the mesenchymal GBM phenotype. A TCF4-miR-125b/miR-20b-FZD6 regulatory circuit controls GBM subtype identity. |

NPTX2 physically interacts with FZD6 to promote β-catenin nuclear translocation and activate canonical Wnt/β-catenin target gene expression (MYC, cyclin D1, snail, N-cadherin) in colorectal cancer cells. FZD6 knockdown nearly completely reversed NPTX2-mediated proliferative effects. |

A divergent lncRNA of FZD6 (lncFZD6) drives liver tumor-initiating cell (TIC) self-renewal by interacting with BRG1-embedded SWI/SNF complex and recruiting it to the FZD6 promoter, inducing chromatin remodeling and FZD6 transcription. WNT5A acts as a ligand of FZD6 in this context, activating Wnt/β-catenin signaling in liver TICs in an lncFZD6-BRG1-FZD6-dependent manner. |

FZD6 knockdown in prostate cancer cells impairs DNA double-strand break (DSB) repair and reduces activities of SRC kinase and STAT3. DNA damage repair deficiency following FZD6 loss is mechanistically linked to WEE1 downregulation via PLK1. A CRISPR kinome screen revealed that FZD6 inhibition sensitizes prostate cancer cells to PKMYT1 inhibition. |

Shear stress triggers spatial reorganization of Frizzled6 (Fzd6) at the plasma membrane through a Vangl1-dependent mechanism. Membrane enrichment of Vangl1 (via Coronin1C-dependent endo/exocytosis shift) results in mutual exclusion of core PCP proteins Fzd6 and Vangl1, augmenting differential junctional and cytoskeletal dynamics along the flow axis in endothelial cells to coordinate collective cell alignment and vessel sprouting. |

FZD6 overexpression promotes nuclear translocation of β-catenin, reduces NLRP3/caspase-1/GSDMD-mediated pyroptosis, and increases 5-FU resistance in colorectal cancer cells. Conversely, FZD6 knockdown decreases nuclear β-catenin, enhances pyroptosis, and reduces 5-FU resistance, establishing a FZD6→β-catenin nuclear translocation→pyroptosis suppression axis. |
