ATMIN interacts with ATM through a C-terminal motif (also present in NBS1), is required for ATM signaling induced by chloroquine and hypotonic stress (but not ionizing radiation-induced DSBs), and ATMIN and ATM mutually stabilize each other's protein levels. |

NBS1 and ATMIN directly compete for ATM binding to control ATM signaling pathway choice: absence of ATMIN increases flux through the NBS1/IR pathway, and absence of NBS1 increases ATMIN-dependent ATM signaling; double deficiency completely abrogates ATM signaling and causes profound radiosensitivity. |

UBR5 (E3 ubiquitin ligase) interacts with ATMIN and ubiquitinates ATMIN at lysine 238 in an IR-stimulated manner; this ubiquitination decreases ATMIN's interaction with ATM and promotes MRN-mediated (NBS1-dependent) ATM signaling after DNA damage. Mutation of ATMIN K238 prevents ATMIN dissociation from ATM and inhibits NBS1 foci formation, checkpoint activation, and increases radiosensitivity. |

Monoubiquitinated PCNA (a marker of stalled replication forks) interacts with ATMIN via WRNIP1, and RAD18 (E3 ligase for PCNA monoubiquitination), WRNIP1, and ATMIN are specifically required for ATM signaling and 53BP1 focus formation induced by replication stress but not by ionizing radiation. |

NEGATIVE RESULT: ASCIZ/ATMIN is dispensable for ATM activation and phosphorylation of KAP1, p53, and H2AX in response to the replication-blocking agent aphidicolin, in both immortalized and primary ASCIZ/ATMIN-deficient MEFs and human ASCIZ/ATMIN-deleted lymphoma cells. |

ASCIZ (ATMIN) forms nuclear foci in response to DNA methylating agents (but not DSB-inducing agents), acts as a lesion-specific scaffold that recruits Rad51 and promotes Rad51 focus formation in response to base methylation damage in an MLH1-dependent manner; ASCIZ depletion dramatically increases apoptosis after methylating DNA damage. |

ATMIN is required for ATM signaling in response to oxidative stress: atmin-null MEFs show reduced ATM phosphorylation and substrate phosphorylation after acute oxidative stress, accumulate DNA damage and prematurely senesce at atmospheric oxygen, and this defect is rescued by antioxidant or physiological oxygen. Conditional neural ATMIN deletion impairs aging-induced ATM signaling and causes accumulation of DNA damage in the aging cortex. |

ASCIZ (ATMIN) directly binds the Dynll1 promoter via its Zn2+ finger domain and transcriptionally activates DYNLL1 expression; DYNLL1 protein in turn binds to ten sites in the ASCIZ transcriptional activation domain and inhibits ASCIZ transcriptional activity, forming a negative feedback loop that auto-regulates DYNLL1 levels. DYNLL1 levels are reduced ~10-fold in ASCIZ-deficient human, mouse, and chicken cells. |

ASCIZ regulates B cell development by activating DYNLL1 expression; ASCIZ-deficient B cell precursors have highly reduced DYNLL1 levels, the B cell lymphopenia in ASCIZ-deficient mice can be fully suppressed by deletion of the pro-apoptotic DYNLL1 target Bim, or rescued by ectopic DYNLL1 expression, placing ASCIZ upstream of DYNLL1 and Bim in B cell survival. |

ATMIN functions as a transcriptional regulator required for ciliogenesis primarily by controlling Dynll1 expression; depletion of ATMIN or DYNLL1 in cultured cells causes ciliary shortening and bulging similar to retrograde IFT mutants, and this is rescued by ectopic DYNLL1 or DYNLL2 expression. DYNLL1 and DYNLL2 localize to cilia in puncta consistent with IFT particles and physically interact with WDR34. |

Deletion of Dynll1 or its transcriptional regulator Asciz, or mutation of DYNLL1 binding motifs in 53BP1, compromises class switch recombination and renders BRCA1-mutant cells and tumors resistant to PARP inhibitor treatment. |

PPARγ promotes UBR5 E3 ligase activity targeting ATMIN: PPARγ depletion increases ATMIN protein levels independent of transcription and suppresses DDR-induced ATM signaling; blocking ATMIN in this context restores ATM activation and DNA repair. In PAH patient PAECs, disrupted PPARγ-UBR5 interaction leads to heightened ATMIN expression and unresolved DNA damage. |

ASCIZ deficiency in chicken DT40 B lymphocytes markedly increases Ig gene conversion rates, while ASCIZ overexpression reduces it below wild-type levels; ASCIZ loss suppresses the MMS hypersensitivity of polβ-deficient cells, indicating ASCIZ influences base repair pathway choice by reducing substrate availability for Ig gene conversion without directly controlling homologous recombination or abasic site formation. |
