In the nucleus, ADNP is a core subunit of a chromatin-remodeling complex, binding BRG1 and other SWI/SNF core subunits through its C-terminus [PMID:25169753] and recruiting the CHD4 helicase together with BRG1 (the ChAHP complex) to specific loci, where it converts pioneer-factor binding into active histone modification and DNA accessibility [PMID:37285842, PMID:39808658]. ADNP occupies defined promoters and chromatin regions—repressing endoderm genes while enhancing neurogenesis and organogenesis programs [PMID:17222401], binding the β-globin locus control region to drive erythroid maturation [PMID:23071114], and counteracting stable CTCF occupancy at SINE B2 elements to enforce H3K9me3 deposition and transcriptional silencing during preimplantation development [PMID:38479840].
