CBF-C (NF-YC) is required together with CBF-A (NF-YB) and CBF-B (NF-YA) to form a CBF/NF-Y–DNA complex. CBF-A and CBF-C interact with each other to form a heterodimer, and CBF-B does not interact with CBF-A or CBF-C individually but associates with the CBF-A–CBF-C complex. All three subunits are present in the protein–DNA complex. |

The C-terminal HAP2-homology domain of NF-YA (CBF-B) is necessary and sufficient for interaction with NF-YB and for DNA binding. This domain contains two functionally separable subdomains: a 21-amino-acid stretch mediating subunit association and a distinct short segment mediating DNA interaction. DNA-binding mutants of NF-YA act as dominant repressors of NF-Y–DNA complex formation and NF-Y-dependent transcription. |

CBF-B (NF-YA) interacts simultaneously with both subunits of the CBF-A–CBF-C heterodimer (NF-YB and NF-YC) to form a heterotrimeric molecule. The evolutionarily conserved histone-fold-like segment of CBF-C (NF-YC), homologous to H2A, is required for CBF-DNA complex formation and mediates interaction with CBF-A (NF-YB). Two separate domains in CBF-C interact with CBF-B (NF-YA), flanking the CBF-A interaction domain, suggesting a tridentate interaction surface. |

Transcriptional activation by the CBF/NF-Y heterotrimer is mediated by two distinct activation domains: one in CBF-B (NF-YB) and one in CBF-C (NF-YC); these act additively in vitro. CBF-A (NF-YA) itself does not contribute an activation domain in this assay. Both activation domains are glutamine- and hydrophobic-residue-rich, similar to Sp1. |

NF-YA protein levels are regulated post-translationally by ubiquitylation and acetylation. Four C-terminal lysines are ubiquitylation targets (mutation stabilizes the protein). Two of these lysines are acetylated in vitro by p300, indicating competition between ubiquitylation and acetylation. A degradation-resistant NF-YA leads to sustained expression of mitotic cyclin complexes and increased cell proliferation. |

Transcriptional activation of RGS4 in confluent PC6 cells is mediated by NF-YA binding to an inverted CCAAT box element (ICE) in the RGS4 promoter. NF-YA nuclear levels increase at confluence, acetylation of NF-YA increases, and dominant-negative NF-YA represses RGS4 promoter activity. NF-YA cooperates with C/EBPβ while Bcl6 (also acetylated) acts as a repressor at a nearby site. |

The short isoform of NF-YA (NF-YAs) is highly expressed in mouse ESCs and declines upon differentiation. A dominant-negative NF-YA mutant reduces expression of stem cell genes. NF-Y binding is required for NANOG association to its genomic loci (30–50% of NANOG peaks contain NF-Y sites). Protein transduction of TAT-NF-YAs compensates for LIF withdrawal in ESC cultures. |

NF-YA (short isoform) is the dominant isoform in neural progenitors and co-expressed with cell cycle genes. Conditional deletion of NF-YA in neural progenitors (nestin-Cre) causes thinning of the cerebral cortex, loss of striatum, progressive decline in neural progenitors, increased apoptosis, and reduced proliferation. ChIP-seq reveals preferential NF-Y binding to cell cycle gene promoters. Forced expression of the long NF-YA isoform in neural progenitors reduces neuronal count, revealing an isoform switch during neuronal differentiation. |

NFYA regulates two sequential waves of transcriptional activation during oocyte-to-embryo transition: primordial follicle oocyte activation (PFA) and zygotic genome activation (ZGA). Oocyte-specific Nfya deletion impairs open chromatin establishment and transcription during PFA, causing ferroptosis and early folliculogenesis failure. Acute NFYA depletion in zygotes causes defective ZGA and two-cell embryo arrest. During PFA, NFYA predominantly binds promoters; during ZGA, it predominantly binds enhancers, though it consistently targets chaperone and histone gene promoters in both stages. |
