**Background of Recombinant Human OVOL1 Protein**
OVOL1 (Ovo-like transcriptional repressor 1) is a member of the Ovo/Svb family of evolutionarily conserved zinc-finger transcription factors. It plays a critical role in regulating epithelial-mesenchymal plasticity, a dynamic process essential for embryonic development, tissue homeostasis, and cancer metastasis. OVOL1 functions primarily as a transcriptional repressor that inhibits the epithelial-mesenchymal transition (EMT) by directly suppressing the expression of key mesenchymal genes (e.g., *ZEB1*, *SNAI2*) while promoting epithelial cell characteristics. This dual role positions OVOL1 as a pivotal mediator of cell fate decisions, maintaining epithelial integrity and counteracting pathological processes like fibrosis and tumor progression.
Structurally, OVOL1 contains a conserved C2H2 zinc-finger DNA-binding domain, enabling sequence-specific interactions with target gene promoters. Its activity is modulated by post-translational modifications and signaling pathways, including TGF-β and Wnt. Dysregulation of OVOL1 has been linked to cancers (e.g., breast, prostate) and fibrotic diseases, where its loss correlates with enhanced EMT and aggressiveness.
Recombinant human OVOL1 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), retains the native protein's functional properties. It serves as a vital tool for studying EMT/MET (mesenchymal-epithelial transition) mechanisms, screening therapeutic agents, and elucidating OVOL1’s interactions with downstream targets or regulatory partners. Its applications extend to *in vitro* assays, structural studies, and developing strategies to restore epithelial homeostasis in diseases driven by EMT dysregulation.
