VEZF1 (vascular endothelial zinc finger 1) is a transcription factor that plays crucial roles in cardiovascular biology and cellular regulation. As a transcriptional regulator, VEZF1 binds to CT/GC-rich DNA regions and specifically interacts with guanine quadruplex (G4) DNA structures to modulate gene expression 1. The protein functions through direct DNA binding and protein-protein interactions, including partnerships with TEAD-1 transcription factor 2. VEZF1 regulates multiple cellular processes including cardiac muscle contraction, endothelial cell differentiation, and angiogenesis by controlling target genes such as MYH7/β-MHC, VASH1, SPOP, and PAQR4 2134. Disease associations include dilated cardiomyopathy, where VEZF1 expression is decreased in diseased human myocardium and regulates compensatory cardiac growth and contractile function 2. Additionally, VEZF1 demonstrates oncogenic properties in hepatocellular carcinoma and bladder cancer, where it promotes tumor progression through transcriptional activation of pro-tumorigenic genes 43. The protein's stability is regulated by post-translational modifications including ubiquitination by STUB1 and O-GlcNAcylation by GFAT1 45. VEZF1's reduced expression has also been observed in suicide-related brain samples, suggesting broader neurobiological relevance 6.
