WSTF forms a two-subunit chromatin remodeling complex (WICH) with the ISWI ATPase (SNF2H in mouse, ISWI in Xenopus), purified to homogeneity; the complex catalyzes assembly of regularly spaced nucleosomal arrays in vitro and localizes to pericentric heterochromatin coincident with its replication. |

The WSTF bromodomain binds acetylated histones and is required for WINAC complex association with chromatin and ligand-induced VDR-mediated transrepression of the 1α-hydroxylase (CYP19A1) gene; a bromodomain deletion mutant acts as a dominant-negative. |

The WICH complex (WSTF-SNF2h) interacts with nuclear myosin 1 (NM1) and associates with RNA polymerase I and rDNA; RNAi knockdown of WSTF reduces pre-rRNA synthesis in vivo, and antibodies to WSTF inhibit Pol I transcription on chromatin but not naked DNA. |

WSTF-SNF2h (WICH) is part of a larger ~3 MDa assembly called B-WICH that also contains NM1, Sf3b155, RNA helicase II/Gualpha, Myb-binding protein 1a, CSB, and the proto-oncogene Dek; WSTF-SNF2h-NM1 is associated with RNA Pol III genes (5S rRNA, 7SL), and post-transcriptional silencing of WSTF reduces these Pol III transcripts. |

WSTF is an indispensable shared subunit of both WINAC (SWI/SNF-type) and WICH (ISWI-type) complexes in vivo: WSTF knockout mice show neonatal lethality with cardiovascular defects linked to impaired WINAC-dependent transcription at the Gja5 promoter, and impaired WICH-dependent SNF2H recruitment to PCNA and reduced cell survival after DNA damage—each defect rescued by overexpression of the respective complex components. |

WSTF-generated constitutive H2AX-pTyr142 associates with RNA polymerase II and active transcription; ATM-dependent EYA1/3 phosphatases remove this mark to silence transcription at DNA damage sites; subsequent re-phosphorylation by WSTF translocating to lesions facilitates transcription-coupled homologous recombination (TC-HR) in G1, using RNAPII-dependent RNA as donor templates. |

WSTF is acetylated at Lys426 by MOF acetyltransferase and deacetylated by SIRT1; MSL1v1 bridges WSTF and MOF for this acetylation. K426 acetylation promotes WSTF Ser158 phosphorylation and enhances both kinase and transcriptional regulatory activities of WSTF. |

WSTF overexpression activates PI3K/Akt and IL-6/STAT3 oncogenic signaling pathways to promote EMT (upregulation of fibronectin, N-cadherin, Snail, Slug, Twist; downregulation of E-cadherin) and increases lung cancer cell proliferation and invasion; these effects are reversed by PI3K or STAT3 inhibitors. |

BAZ1B (as part of the WICH complex) interacts with ATAD5, and the BAZ1B-binding region on ATAD5 overlaps the UAF1-binding domain; BAZ1B binding to ATAD5 prevents premature de-ubiquitination of mono-ubiquitinated PCNA after oxidative DNA damage, and disruption of this interaction increases cellular sensitivity to oxidative stress. |

During chronic (but not acute) inflammation, WSTF interacts with the ATG8 autophagy protein family in the nucleus, leading to WSTF nuclear export and degradation by autophagosomes/lysosomes; loss of WSTF opens chromatin over inflammatory genes and amplifies NF-κB-driven inflammation; cell-penetrating peptides blocking WSTF-ATG8 interaction suppress chronic inflammation in MASH and osteoarthritis mouse models. |

BAZ1B (WSTF) is dispensable for H2AX Tyr142 phosphorylation on sex chromosomes during meiosis and for male fertility; conditional BAZ1B deletion in spermatocytes causes ectopic γH2AX on synapsed autosomes at early pachytene but does not affect sex chromosome silencing or SNF2H localization during meiosis—demonstrating context-dependent roles distinct from somatic cells. |

WSTF localizes to promoters and gene bodies of actively transcribed loci together with co-activators ASH2L and CBP; WSTF loss depletes ASH2L/CBP at these loci, causes loss of H3K4me2 and multiple acetylation marks, gain of Polycomb components, widespread isoform switching, and activates Wnt/β-catenin signaling—with TCF7L2 showing locus-specific isoform switching due to gene-body loss of active marks. |
