Abstract

Chromodomain, helicase, DNA-binding protein 8 (CHD8) is an ATP-dependent chromatin remodeling enzyme that has been demonstrated to exist within a large protein complex which includes WDR5, Ash2L, and RbBP5, members of the Mixed Lineage Leukemia (MLL) histone modifying complexes. Here we show that CHD8 relocalizes to the promoter of the MLL regulated gene HOXA2 upon gene activation. Depletion of CHD8 enhances HOXA2 expression under activating conditions. Furthermore, depletion of CHD8 results in a loss of the WDR5/Ash2L/RbBP5 subcomplex, and consequently H3K4 trimethylation, at the HOXA2 promoter. These studies suggest that CHD8 alters HOXA2 gene expression and regulates the recruitment of chromatin modifying enzymes.Structured summaryMINT-7542810: CHD8 (uniprotkb:Q9HCK8) physically interacts (MI:0915) with RbBP5 (uniprotkb:Q15291) by anti tag coimmunoprecipitation (MI:0007)MINT-7542794: CHD8 (uniprotkb:Q9HCK8) physically interacts (MI:0915) with WDR5 (uniprotkb:P61964) by anti tag coimmunoprecipitation (MI:0007)MINT-7542820: CHD8 (uniprotkb:Q9HCK8) physically interacts (MI:0915) with ASH2L (uniprotkb:Q9UBL3) by anti tag coimmunoprecipitation (MI:0007)MINT-7542769: CHD8 (uniprotkb:Q9HCK8) physically interacts (MI:0914) with RbBP5 (uniprotkb:Q15291), ASH2L (uniprotkb:Q9UBL3) and WDR5 (uniprotkb:P61964) by anti tag coimmunoprecipitation (MI:0007)
