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. {ECO:0000269PubMed:17938208, ECO:0000269PubMed:18378692}.

Subcellular Localization

Nucleus {ECO:0000269PubMed:18378692, ECO:0000269PubMed:20453063}. Note=Localizes to the promoter regions of several CTNNB1-responsive genes. Also present at known CTCF target sites.

Disease Associations

Autism 18 (AUTS18) [MIM:615032]: A complex multifactorial, pervasive developmental disorder characterized by impairments in reciprocal social interaction and communication, restricted and stereotyped patterns of interests and activities, and the presence of developmental abnormalities by 3 years of age. Most individuals with autism also manifest moderate mental retardation. {ECO:0000269PubMed:23160955}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
