MZF1 (Myeloid Zinc Finger 1) is a nuclear-localized transcription factor belonging to the SCAN domain-containing zinc finger protein family, a lineage of regulatory proteins characterized by the presence of a SCAN domain that mediates protein-protein interactions and tandem zinc finger motifs that facilitate sequence-specific DNA binding. Structurally, the MZF1 protein consists of an N-terminal domain responsible for transcriptional activation and a C-terminal region containing multiple zinc finger domains that recognize specific DNA sequences to modulate the transcription of downstream target genes. This gene is predominantly expressed in myeloid lineages, including granulocytes and macrophages, where it plays a critical role in maintaining normal hematopoiesis, cell proliferation, and differentiation. Dysregulation of MZF1 function, whether through mutations that impair DNA binding or transcriptional activity, or through aberrant expression levels, is strongly implicated in the pathogenesis of hematologic malignancies such as acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Specifically, MZF1 overexpression can drive uncontrolled cell proliferation and inhibit differentiation, thereby increasing tumor risk, whereas reduced expression may lead to hematopoietic dysfunction and impaired immune cell development. Beyond hematopoietic disorders, MZF1 is involved in tumor progression in solid cancers, including breast and liver cancer, by regulating key effectors such as the cell cycle regulator Cyclin D1 and apoptosis-related genes, highlighting its broader significance in cellular homeostasis and oncogenesis.
