General annotation (Comments)
| Function | DNA helicase that acts as a chromatin remodeling factor and regulates transcription. Acts as a transcription repressor by remodeling chromatin structure and recruiting histone H1 to target genes. Suppresses p53/TP53-mediated apoptosis by recruiting histone H1 and preventing p53/TP53 transactivation activity. Acts as a negative regulator of Wnt signaling pathway by regulating beta-catenin (CTNNB1) activity. Negatively regulates CTNNB1-targeted gene expression by being recruited specifically to the promoter regions of several CTNNB1 responsive genes. Involved in both enhancer blocking and epigenetic remodeling at chromatin boundary via its interaction with CTCF. Acts as a suppressor of STAT3 activity by suppressing the LIF-induced STAT3 transcriptional activity. Also acts as a transcription activator via its interaction with ZNF143 by participating to efficient U6 RNA polymerase III transcription. Ref.1 Ref.6 |
| Subunit structure | Component of some MLL1/MLL complex, at least composed of the core components MLL, ASH2L, HCFC1/HCF1, WDR5 and RBBP5, as well as the facultative components C17orf49, CHD8, E2F6, HSP70, IN80C, KIAA1267, LAS1L, MAX, MCRS1, MGA, MYST1/MOF, PELP1, PHF20, PRP31, RING2, RUVB1/TIP49A, RUVB2/TIP49B, SENP3, TAF1, TAF4, TAF6, TAF7, TAF9 and TEX10 By similarity. Interacts with p53/TP53, histone H1, CTNNB1, CTCF and PIAS3. Component of a multiprotein complex of 900 kDa containing WDR5. |
| Subcellular location | Nucleus. Note: Localizes to the promoter regions of several CTNNB1-responsive genes. Also present at known CTCF target sites. Ref.1 |
| Developmental stage | Expressed predominantly from early- to mid-stage mouse embryogenesis. Detected throughout embryos from E7.5 to E9.5 but localizes predominantly in the brain, faces, branchial arches, limb buds, and tail buds of embryos at E10.5. Ref.2 |
| Post-translational modification | Sumoylated By similarity. |
| Disruption phenotype | Death during early embryogenesis due to widespread apoptosis. Embryos manifest growth retardation from E5.5 and developmental arrest accompanied by massive apoptosis at E7.5. They develop into an egg cylinder but do not form a primitive streak or mesoderm. Mice lacking both Tp53 and Chd8 ameliorate this developmental arrest. Ref.6 Ref.2 |
| Sequence similarities | Belongs to the SNF2/RAD54 helicase family. CHD8 subfamily. Contains 2 chromo domains. Contains 1 helicase ATP-binding domain. Contains 1 helicase C-terminal domain. |
| Sequence caution | The sequence BAC98203.2 differs from that shown. Reason: Miscellaneous discrepancy. Partially unspliced pre-RNA. |
