ZNF281 expression is directly induced by SNAIL at the transcriptional level and repressed by miR-34a/b/c (which is itself repressed by SNAIL), forming a coherent feed-forward loop. ZNF281 in turn directly activates SNAIL transcription, creating a regulatory circuit controlling EMT. p53 activation represses ZNF281 via miR-34a. |

GSK-3β (but not GSK-3α) phosphorylates ZNF281 at a consensus TSGEHS motif (S638), which promotes ZNF281 interaction with the E3 ligase β-TrCP2, leading to ubiquitination and proteasomal degradation of ZNF281. 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, on PARP activity. ZNF281 binds XRCC4 through its zinc-finger domain and facilitates XRCC4 recruitment to damage sites, promoting efficient NHEJ repair. |

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