Batf3 deletion ablates development of CD8α+ dendritic cells in vivo, demonstrating that Batf3 is required for this DC lineage. Batf3-/- mice are defective in cross-presentation of cell-associated antigens and lack virus-specific CD8+ T cell responses, establishing Batf3-dependent DCs as essential mediators of cross-presentation. |

p21(SNFT)/BATF3 forms a heterodimer with Jun on AP-1 binding sites (TRE) and a trimolecular complex with Jun and NF-AT at the distal NF-AT/AP-1 composite element. Replacement of Fos by p21(SNFT) in this complex drastically alters protein-DNA contacts, and p21(SNFT)/Jun binds the NF-AT/AP-1 element cooperatively with NF-AT but with significantly reduced efficiency compared to Fos/Jun. This altered complex conformation underlies specific repression of the IL-2 promoter and AP-1-driven composite promoter elements. |

Batf3 maintains autoactivation of Irf8 at a CD8α+ cDC-specific enhancer containing multiple AP1-IRF composite elements (AICEs) within the Irf8 superenhancer. After specification of pre-CD8 DC progenitors (which requires IRF8 but not Batf3), Batf3 becomes required for continued Irf8 autoactivation; CDPs from Batf3-/- mice fail to complete CD8α+ cDC development due to decay of Irf8 expression and divert to the CD4+ cDC lineage. |

Batf3 and Id2 have a synergistic effect on Irf8-directed CD8α+ DC development; Irf8 is upstream of Batf3 and Id2 in the developmental program; without Irf8, expression of Id2 and Batf3 alone is insufficient for CD8α+ DC development. |

CD8α+ DCs can emerge independently of Batf3 (as well as Id2 and Nfil3) in short-term bone marrow reconstitution, but only Irf8 is essential for CD8α+ DC development. These Batf3-independent CD8α+ DCs retain cross-presentation capacity. In contrast, CD103+ DC development requires all four factors including Batf3. |

BATF3 and IRF4 cooperatively drive ATLL-specific gene expression; BATF3 knockdown reduces proliferation and survival of ATLL cell lines. HBZ (the HTLV-I-encoded transcription factor) binds to an ATLL-specific BATF3 super-enhancer and regulates BATF3 expression and its downstream targets including MYC. BET inhibitors collapse this HBZ-BATF3 transcriptional network. |

BATF3 binds directly to the MYC promoter and MYC is a critical BATF3 target. JAK/STAT signaling (including STAT proteins directly binding the BATF3 locus by ChIP) regulates BATF3 expression. |

BATF3 has a T cell-intrinsic role in programming CD8+ T cell survival and memory. BATF3 is expressed transiently after T cell priming. T cells lacking Batf3 show normal expansion but undergo aggravated contraction and produce diminished memory responses. BATF3 overexpression in CD8+ T cells promotes survival and memory transition. Mechanistically, BATF3 regulates T cell apoptosis and longevity via the pro-apoptotic factor BIM. |
