The PHD finger of BPTF specifically recognizes histone H3 trimethylated at K4 (H3K4me3) through anti-parallel beta-sheet formation on the PHD finger surface, with the long side chains of R2 and K4me3 fitting into adjacent pre-formed surface pockets bracketing an invariant tryptophan. Crystal and NMR structures of the bromodomain-proximal PHD finger in free and H3K4me3-bound states were determined, and key specificity-determining residues were identified by point mutagenesis. |

BPTF (NURF301), the largest subunit of the NURF complex, together with the ISWI ATPase is necessary and sufficient for accurate and efficient nucleosome sliding in vitro. An HMGA/HMGI(Y)-like domain of NURF301 facilitates nucleosome sliding, implicating DNA conformational changes in the sliding mechanism. NURF301 also directly interacts with sequence-specific transcription factors, providing a basis for targeted recruitment of the NURF complex to specific genes. |

In Drosophila, alternative splicing of NURF301/BPTF generates distinct NURF complexes with differing histone modification binding specificities. Full-length NURF301 contains a C-terminal bromodomain and PHD finger that bind H3K4me3 and H4K16Ac respectively; a truncated isoform lacking these domains assembles a complex deficient in these marks. Full-length NURF301 (but not the truncated isoform) is required for spermatogenesis and expression of spermatid differentiation genes. |

The conformation of histone H3 tails within nucleosomes is inhibitory to BPTF PHD finger binding. The H3 tails interact robustly but dynamically with nucleosomal DNA, substantially reducing PHD finger association compared to free peptide. Altering the electrostatics of the H3 tail via post-translational modification or mutation increases accessibility to the PHD finger, indicating that PTM crosstalk regulates effector domain binding by altering nucleosome conformation. |

Bptf is required in mouse embryos for establishment of a functional distal visceral endoderm and proper gastrulation. Bptf-null embryos implant but fail to establish anterior visceral endoderm and primitive streak. Bptf physically and functionally interacts with Smad transcription factors (Smad2/3) and may co-regulate gene targets of the TGF-β/Smad pathway essential for early mouse development. |

BPTF physically interacts with c-MYC and is required for the full c-MYC transcriptional program in fibroblasts. BPTF knockdown leads to decreased c-MYC recruitment to DNA and changes in chromatin accessibility. In Bptf-null MEFs, BPTF is necessary for c-MYC-driven proliferation, G1-S progression, and replication stress but not c-MYC-driven apoptosis. In vivo, Bptf inactivation in pre-neoplastic pancreatic acinar cells significantly delays tumor development. |

FAC1 represses ZF87/MAZ-induced transcriptional activation of the SV40 promoter in a dose-dependent manner, and a FAC1 deletion mutant lacking the ZF87/MAZ interaction domain does not suppress ZF87/MAZ activation. |

BPTF regulates androgen receptor (AR) activity in prostate cancer by increasing chromatin accessibility at AR binding sites (through SMARCA1, the catalytic NURF subunit) and by forming a protein complex with AR and FOXA1 in which FOXA1 recruits the BPTF-AR complex to chromatin while BPTF stabilizes the AR-FOXA1 interaction. BPTF interacts with AR through its bromodomain, and bromodomain inhibition disrupts this interaction and impairs AR signaling. |

Molecular dynamics simulations reveal that BPTF PHD finger and bromodomain adopt distinct conformational states depending on binding context; nucleosome engagement induces compaction of the multidomain structure. PHD finger binding displaces the H3 tail from nucleosomal DNA, increasing H3 tail flexibility and promoting compensatory binding of the H4 tail to DNA, weakening overall hydrogen bonding with DNA and suggesting localized nucleosome destabilization. |
