ZFHX1A (Zinc Finger Homeobox 1A), also known as ATBF1 (AT-binding transcription factor 1), is a transcription regulatory protein encoded by the ZFHX1A gene. It belongs to the zinc finger-homeodomain protein family, characterized by a unique combination of zinc finger motifs and homeodomains that enable DNA binding and interaction with other regulatory proteins. Structurally, ZFHX1A contains multiple functional domains, including four homeodomains and 23 zinc finger motifs, which contribute to its role in transcriptional repression or activation.
Originally identified as a tumor suppressor, ZFHX1A plays critical roles in cellular differentiation, development, and cancer progression. It regulates gene expression by binding to AT-rich sequences in promoter regions of target genes, influencing processes such as cell cycle control, apoptosis, and epithelial-mesenchymal transition (EMT). Studies link ZFHX1A dysfunction to various cancers, including prostate, breast, and gastric cancers, where its downregulation often correlates with metastasis and poor prognosis. Additionally, it interacts with signaling pathways like TGF-β and Wnt, modulating cellular responses to environmental cues.
Recombinant ZFHX1A protein is engineered using expression systems like Escherichia coli or mammalian cells, followed by purification via affinity chromatography. This recombinant form retains native binding activity and is widely used in biochemical assays, structural studies, and functional investigations. Researchers employ it to elucidate molecular mechanisms underlying cancer biology, neuronal development, and tissue homeostasis. Its application extends to drug discovery, where it aids in screening compounds targeting transcriptional regulation. Quality control typically involves SDS-PAGE, Western blotting, and functional validation through DNA-binding assays.
Overall, ZFHX1A recombinant protein serves as a vital tool for dissecting its multifaceted roles in health and disease, offering insights into therapeutic strategies for cancers and developmental disorders.
