ZNF281 is directly transcriptionally induced by SNAIL (EMT transcription factor) and directly repressed by miR-34a/b/c, forming a coherent feed-forward loop. ZNF281 in turn directly activates SNAIL transcription, and ectopic ZNF281 induces EMT, increases migration/invasion, β-catenin activity, stemness markers LGR5/CD133, and sphere formation. Knockdown causes MET and inhibits lung metastases in mice. c-MYC induces ZNF281 protein in a SNAIL-dependent manner, and ZNF281 inactivation prevented EMT induced by c-MYC or SNAIL. |

ZNF281 transcriptionally activates XRCC2 (homologous recombination) and XRCC4 (NHEJ) through direct DNA-binding at their promoters. Cells silenced for ZNF281 show delayed DNA repair after etoposide treatment. c-MYC also binds the same promoters but cannot activate transcription or modify ZNF281 activity. |

GSK-3β (not GSK-3α) phosphorylates ZNF281 at a consensus TSGEHS motif (S638), promoting interaction of ZNF281 with β-TrCP2 (not β-TrCP1), leading to ZNF281 ubiquitination and proteasomal degradation. A ZNF281-S638A mutant is resistant to this degradation. ZNF281 also transcriptionally represses β-TrCP2, forming a negative feedback loop. |

ZNF281 is rapidly recruited to DNA double-strand break sites (within seconds of damage) via a mechanism dependent on its DNA-binding domain and, at least in part, PARP activity. ZNF281 physically binds XRCC4 through its zinc-finger domain and facilitates XRCC4 recruitment to damage sites. Depletion of ZNF281 impairs NHEJ efficiency and decreases cell viability after DNA damage. |

ZNF281 (Zfp281) physically associates with the master erythroid transcription factor GATA1, co-occupies many chromatin sites with GATA1 and Zfp148, and regulates a common set of erythroid differentiation genes. Combined deficiency of Zfp148 and Zfp281 causes a marked erythroid maturation block, demonstrating functional redundancy. |

ZNF281 transactivates the EMT-related transcription factors ZEB1 and Snail. Both ZEB1 and Snail can transcriptionally suppress miR-543 expression, while miR-543 directly targets ZNF281, establishing a ZNF281-miR-543 feedback loop that regulates TGF-β-induced breast cancer metastasis. |

SUFU binds ZNF281 and masks its nuclear localization signal (NLS), causing cytoplasmic retention of ZNF281, thereby suppressing ZNF281-induced tumor cell migration and DNA damage repair. SUFU also hampers interactions between ZNF281 and promoters of target genes. This defines a Hedgehog-independent anti-tumor role for SUFU. |

ZNF281 suppresses transcription of TFAM, NRF1, and PGC-1α (mitochondrial biogenesis regulators), and physically interacts with NRF1 and PGC-1α. ZNF281 is recruited to the promoter regions of TFAM, TFB1M, and TFB2M to repress their expression. Knockdown of ZNF281 increases mitochondrial content, OCR, and TCA cycle intermediates, and knockdown of TFAM reverses these effects. This suppression of mitochondrial biogenesis facilitates HCC invasion and metastasis. |

ZNF281 interacts with the ANXA10 promoter at ZNF281 recognition sites and recruits components of the NuRD complex (including HDAC1 and MTA1) to transcriptionally repress tumor suppressor ANXA10. Knockdown of HDAC1 or MTA1 releases ANXA10 from repression and reverses EMT, invasion, and metastasis driven by ZNF281. |

ZNF281 upregulates the RIPK1/RIPK3/MLKL necroptosis signaling axis in hepatocytes under free fatty acid stress, promoting lipid accumulation and inflammatory cell death in NASH. Hepatocyte-specific Zfp281 knockout prevents NASH diet-induced liver injury, steatosis, inflammation, and fibrosis. Pterostilbene was identified as a ZNF281 inhibitor that recapitulates these protective effects. |

Anticancer agents (intercalating/alkylating agents, tyrosine kinase inhibitors, receptor inhibitors) converge to increase selective translational upregulation of ZNF281 in cardiomyocytes as part of the integrated stress response. Cardiomyocyte-specific ZNF281-deficient mice are resistant to anthracycline-induced cardiotoxicity, while cardiomyocyte-specific ZNF281-overexpressing mice develop cardiotoxicity features. A small-molecule inhibitor ZIM prevented anthracycline-induced cardiotoxicity and enhanced anti-tumor effects. |
