VEZF1/DB1 localizes to the nucleus and directly activates transcription driven by the human endothelin-1 (ET-1) promoter by binding a specific 6-bp element (ACCCCC) located 47 bp upstream of the ET-1 transcription start site; a 2-bp mutation in this element abolished responsiveness, and recombinant VEZF1 was shown to bind this sequence directly. |

Targeted inactivation of Vezf1 in mice reveals dose-dependent roles in blood vascular and lymphatic development: homozygous null embryos display vascular remodeling defects, loss of vascular integrity, hemorrhaging, and defective endothelial cell adhesion and tight junction formation; heterozygous embryos show lymphatic hypervascularization and edema (cystic hygroma-like phenotype). |

Deletion of both copies of Vezf1 in mouse embryonic stem cells causes genome-wide loss of DNA methylation at LINE1 elements, minor satellite repeats, imprinted genes, and CpG islands, associated with a substantial decrease in the de novo DNA methyltransferase Dnmt3b, establishing VEZF1 as an upstream regulator of Dnmt3b expression and global DNA methylation. |

The transcription factor DB1/VEZF1 physically interacts with prenylated RhoB (but weakly with RhoA and not with H-Ras); the RhoB-binding domain in DB1 is upstream and separable from the zinc finger DNA-binding domain; RhoB inhibits transcriptional activation by DB1, whereas RhoA and Ras have little or no effect; prenylated RhoB species were identified in the nuclear membrane and intranuclear laminar region where they can associate with DB1. |

VEZF1 acts as a barrier element factor that protects gene promoters from de novo DNA methylation independently of histone acetylation or transcription; the methylation-protection activity of VEZF1 is separable from the CTCF-dependent enhancer-blocking and USF-dependent histone modification functions of the HS4 insulator; VEZF1 elements are sufficient to mediate demethylation and protection of the APRT CpG island promoter. |

Genome-wide, VEZF1 binding sites in HeLaS3 cells are strongly correlated with peaks of elongating Ser2-phosphorylated RNA Polymerase II, indicating VEZF1-dependent slowing of Pol II elongation; in Vezf1-null mouse ESCs, accumulation of elongating Pol II near Vezf1 binding sites in the Dnmt3b gene and other loci is significantly reduced; VEZF1 binding near cassette exons can influence alternative splicing; VEZF1 physically interacts with Mrg15/Mrgbp, a protein that recognizes H3K36 trimethylation. |

In Vezf1-null mouse ESCs, expression of the antiangiogenic factor Cited2 is significantly increased; Vezf1-null ESCs show defective differentiation into endothelial cells with reduced activation of EC-specific genes and lower H3K27 acetylation at their promoters; shRNA depletion of Cited2 significantly rescues the angiogenic defects of Vezf1-null ECs; Vezf1 can block inappropriate promoter-enhancer interactions, preventing aberrant promoter activation. |

VEZF1 binds directly to DNA guanine quadruplex (G4) structures both in vitro and in cells; VEZF1-G4 interaction modulates the ratio of VASH1A/VASH1B mRNA isoforms via alternative polyadenylation; disruption of VEZF1-G4 interaction (by VEZF1 depletion or G4-stabilizing small molecules) increases the long VASH1A isoform and elevates tubulin detyrosinase activity; loss of VEZF1-G4 interaction in HUVECs diminishes angiogenesis. |
