MafF encodes a small nuclear bZIP protein lacking the amino-terminal acidic transactivation domain present in c-Maf; when overexpressed via retroviral vector in CEF cells, MafF did not induce morphological transformation but induced colony formation in soft agar with very low efficiency; MafK protein was detected predominantly in nuclei by immunostaining. |

Human MafF (hMafF) binds specifically to the US-2 element in the oxytocin receptor (OTR) gene promoter, as shown by yeast one-hybrid screening and electrophoretic mobility shift assay (EMSA); hMafF is an 18-kDa protein with a leucine zipper but no transactivation domain, preferentially expressed in term myometrium. |

Murine MafF is dispensable for development: homozygous mafF null mice are born at normal Mendelian ratios with no obvious functional deficiencies, even in tissues where other small Maf proteins are low. The lacZ-knockin revealed prominent mafF expression in gut, lung, liver, heart outflow tract, cartilage, bone membrane, and skin, but not in hematopoietic cells at any developmental stage. mafF is regulated by three distinct promoters. |

MafF can form homodimers and high-affinity heterodimers with CNC-bZip family members Nrf1, Nrf2, and NF-E2. MafF homodimers do not repress transcription (unlike MafG/MafK homodimers) on gamma-globin, beta-globin, and GCSl promoters in multiple cell lines, while MafF/CNC heterodimers act as weak transcriptional activators. MafF shows a specific regulatory role in combination with Jun at the GCSl promoter. |

mafF transcript is differentially induced by electrophile-response-element (EpRE) activators PDTC and PEITC (but not tBHQ) in HepG2 cells, and this induction is transcriptionally mediated; mafF is induced to a greater extent than mafG or mafK. The induction by tBHQ failure suggests that small Maf upregulation is not an absolute requirement for EpRE-mediated gene expression. |

A novel protein MIP (MafF Interacting Protein) physically interacts with hMafF via its coiled-coil domain binding the leucine zipper of hMafF in vitro and in vivo; this interaction causes translocation of MIP from the cytoplasm to the nucleolus in HeLa cells. Co-expression of hMafF and MIP activates US2-element-driven transcription, whereas either alone has no effect, establishing MIP as a co-activator of hMafF. |

sMafs (MafF, MafG, MafK) are bZIP transcription factors that: (1) form homodimers that act as transcriptional repressors (lacking activation domain); (2) form obligatory heterodimers with CNC proteins (NF-E2 p45, Nrf1, Nrf2, Nrf3) and Bach proteins (Bach1, Bach2), which cannot bind DNA as monomers, making sMafs indispensable partners; (3) participate in transcriptional activation or repression depending on heterodimeric partner and context. |

Under non-inflammatory conditions, MAFF positively correlates with LDLR. BACH1 assists MAFF in inflammatory contexts, as revealed by ChIP-mass spectrometry. |

MafF suppresses transcription from the HBV core promoter by physically binding to the HBV core promoter region (ChIP analysis) and competitively inhibiting HNF-4α binding to an overlapping sequence in enhancer II (EnhII). MafF loss (via CRISPR or siRNA) increases HBV core RNA and pgRNA levels. MafF expression is induced by IL-1β or TNF-α in an NF-κB-dependent manner in hepatocytes. |

BAP1 (a nuclear deubiquitinating enzyme) binds to MAFF and deubiquitylates it, primarily removing K48-linked ubiquitin chains, thereby stabilizing MAFF protein. Stabilized MAFF upregulates DUSP5 expression, resulting in inhibition of ERK phosphorylation, which suppresses colorectal cancer cell growth. |
