ID:CHD8_HUMAN DESCRIPTION: RecName: Full=Chromodomain-helicase-DNA-binding protein 8; Short=CHD-8; EC=3.6.4.12; AltName: Full=ATP-dependent helicase CHD8; AltName: Full=Helicase with SNF2 domain 1; 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 in efficient U6 RNA polymerase III transcription. CATALYTIC ACTIVITY: ATP + H(2)O = ADP + phosphate. SUBUNIT: Interacts with p53/TP53, histone H1, CTNNB1, CTCF and PIAS3. 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, INO80C, KANSL1, LAS1L, MAX, MCRS1, MGA, KAT8/MOF, PELP1, PHF20, PRP31, RING2, RUVB1/TIP49A, RUVB2/TIP49B, SENP3, TAF1, TAF4, TAF6, TAF7, TAF9 and TEX10. Interacts with CHD7. INTERACTION: Q9P2D1:CHD7; NbExp=3; IntAct=EBI-4410319, EBI-3951683; SUBCELLULAR LOCATION: Nucleus. Note=Localizes to the promoter regions of several CTNNB1-responsive genes. Also present at known CTCF target sites. PTM: Sumoylated (By similarity). MISCELLANEOUS: Its gene is located in the 14q11.2 region of the genome which is associated with developmental delay, cognitive impairment and similar minor anomalies in some children, suggesting that it may be a good candidate for the phenotype. SIMILARITY: Belongs to the SNF2/RAD54 helicase family. CHD8 subfamily. SIMILARITY: Contains 2 chromo domains. SIMILARITY: Contains 1 helicase ATP-binding domain. SIMILARITY: Contains 1 helicase C-terminal domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
