NSD3/WHISTLE methylates histone H3-K4 and H3-K27 to repress transcription, induces apoptosis via caspase-3 activation dependent on its HMTase activity, and recruits HDAC1 through its N-terminal PWWP region. The SET domain cysteine 297 is critical for HMTase activity, and the PWWP domain is required for HMTase activity by interacting with associating factors. |

NSD3/WHISTLE interacts with heat shock protein HSP90α and the histone demethylase JMJD1C in a complex (identified by immunoaffinity TAP analysis). WHISTLE is recruited to the p450c17 promoter via SF-1 and represses transcription at prepubertal stages; JMJD1C then replaces WHISTLE to activate target gene expression during mouse testis development. |

NSD3 interacts with the extraterminal (ET) domain of BRD4 (and BRD2/BRD3); this interaction is required for pTEFb-independent transcriptional activation. NSD3 is recruited to BRD4 target genes in a BRD4-dependent manner and depletion of BRD4 or NSD3 reduces H3K36 methylation at target genes. |

The PHD5-C5HCH module of NSD3 forms a novel integrated PHD-PHD-like structural module that binds histone H3 N-terminal peptides, recognizing unmodified H3K4 and trimethylated H3K9 (H3K9me3) via PHD5. This binding specificity differs from NSD1 (which does not bind H3 peptides) and NSD2 (which prefers H3K9me0 over H3K9me3). |

NSD3 is required for neural crest specification: it is expressed in premigratory and migratory neural crest cells, and is necessary for expression of neural plate border gene Msx1 and neural crest transcription factors Sox10, Snail2, Sox9, and FoxD3. H3K36me2 at the Sox10 locus specifically requires NSD3. A separate, direct requirement for NSD3-related methyltransferase activity exists during neural crest migration (shown by dominant-negative approach restricted to migratory stages). |

NSD3-NUT fusion oncoprotein is both necessary and sufficient for blockade of differentiation and maintenance of proliferation in NUT midline carcinoma (NMC) cells. NSD3-NUT binds to BRD4, and BRD4 bromodomain inhibitors reverse its oncogenic effects. NSD3 itself is required for the differentiation block in BRD4-NUT-expressing NMC cells. |

AML maintenance by BRD4 requires its interaction with the short isoform of NSD3 (NSD3-short), which lacks the methyltransferase domain. NSD3-short acts as an adaptor linking BRD4 (via BRD4 ET domain) to the CHD8 chromatin remodeler, using a PWWP chromatin reader module and an acidic transactivation domain. BRD4, NSD3, and CHD8 co-localize at super-enhancers across the AML genome and are co-released upon BET inhibition. |

NSD3 directly methylates IRF3 at K366 (monomethylation) via its SET domain; NSD3 binds the IRF3 C-terminal region through its PWWP1 domain (identified by mass spectrometry of IRF3-associated proteins). K366 monomethylation enhances IRF3 transcriptional activity by promoting IRF3 dissociation from protein phosphatase PP1cc, thereby maintaining IRF3 phosphorylation and type I interferon production. NSD3 deficiency impairs antiviral innate immune response in vivo. |

NSD3 long isoform (full-length, with catalytic domain), but not the short isoform lacking the catalytic domain, cooperates with EZH2 and RNA polymerase II to drive H3K36me2/3-dependent transactivation of genes associated with NOTCH receptor cleavage, leading to nuclear accumulation of NICD and NICD-mediated transcriptional repression of E-cadherin. This promotes breast cancer cell stemness, EMT, and metastasis. |

NSD3 is a catalytically active H3K36me2 methyltransferase and a key driver of lung squamous cell carcinoma (LUSC). An LUSC-associated variant NSD3(T1232A) shows increased catalytic activity for H3K36me2 in vitro and in vivo due to structural changes that relieve auto-inhibition. Expression of NSD3(T1232A) accelerates tumorigenesis in mouse models of LUSC. NSD3-dependent oncogenic activity requires its catalytic activity and promotes oncogenic gene expression via chromatin landscape reprogramming. NSD3-amplified/mutant LUSCs are hypersensitive to bromodomain inhibition. |

NSD3 (via its long isoform) mediates chromosome folding in NUT carcinoma cells: it stabilizes the BRD4-NUT fusion oncoprotein on chromatin, promotes H3K36me2, and supports BRD4-NUT nuclear condensates; NSD3 loss attenuates distant chromatin interactions between BRD4-NUT megadomains. In fusion-negative cells, NSD3-short (catalytically inactive) promotes long-range chromatin contacts (>megabases) in a PWWP domain-dependent manner. |
