Fzd5 knockout mice die in utero around E10.75 due to defects in yolk sac and placental angiogenesis, with markedly reduced endothelial cell proliferation (BrdU labeling); Fzd5 specifically synergized with Wnt2, Wnt5a, and Wnt10b in ectopic axis induction assays in Xenopus embryos, establishing Fzd5 as a Wnt receptor required for vascular development. |

CVAK104 is a novel binding partner of both Dishevelled (Dvl) and FZD5 (but not FZD1 or FZD4); CVAK104 selectively induces clathrin-mediated internalization of FZD5 and its subsequent lysosomal degradation, thereby suppressing Wnt/β-catenin signaling; knockdown of CVAK104 increases FZD5 protein levels and activates Wnt signaling. |

A positive feedback loop between Gcm1 and Fzd5 is essential for chorionic branching morphogenesis: Gcm1 upregulates Fzd5 at branching initiation sites, and elevated Fzd5 via nuclear β-catenin signaling maintains Gcm1 expression; Fzd5-mediated signaling also induces disassembly of cell junctions (downregulation of ZO-1, claudin 4, claudin 7) and upregulates Vegf in trophoblast cells. |

A heterozygous frameshift mutation in FZD5 (p.Ala219Glufs*49) produces a truncated protein that retains the WNT-ligand-binding CRD but lacks the transmembrane domain; the truncated protein is secreted from cells and acts as a dominant-negative receptor, antagonizing both canonical and non-canonical WNT signaling and causing coloboma and microphthalmia in zebrafish. |
