ZNF224. a member of the Krüppel-associated box (KRAB) domain-containing zinc finger protein (ZNF) family, functions as a transcriptional repressor involved in diverse cellular processes. Structurally, it contains an N-terminal KRAB domain, which mediates interactions with corepressors like KAP1/TIF1β to recruit chromatin-modifying complexes, and multiple C-terminal C₂H₂-type zinc finger motifs that facilitate DNA binding. This protein is encoded by the *ZNF224* gene located on human chromosome 19q13.4 and exhibits tissue-specific expression, notably in the liver, kidney, and immune cells.
Biologically, ZNF224 regulates genes linked to apoptosis, proliferation, and differentiation. It modulates stress-responsive pathways by interacting with transcription factors such as ATF4. influencing oxidative stress responses. In cancer, ZNF224 demonstrates dual roles: it acts as a tumor suppressor by repressing oncogenes (e.g., *VEGF*), yet paradoxically promotes aggressiveness in some contexts through alternative splicing variants (e.g., ZNF255) or cooperation with polycomb repressive complexes (e.g., PRC2). Studies associate ZNF224 dysregulation with leukemia, breast cancer, and renal fibrosis. Additionally, its interaction with WT1 in the kidneys suggests a role in diabetic nephropathy.
Recombinant ZNF224 protein is utilized to dissect its DNA-binding specificity, repression mechanisms, and therapeutic potential. Research continues to explore its context-dependent functions in disease and homeostasis.
