ARID1A Transcription Factor
AT-rich interaction domain 1A | B120, BAF250, BAF250a, C10rf4, P270, C1orf4, SMARCF1

This gene encodes a member of the SWI/SNF family, whose members have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein is part of the large ATP-dependent chromatin remodeling complex SNF/SWI, which is required for transcriptional activation of genes normally repressed by chromatin. It possesses at least two conserved domains that could be important for its function. First, it has a DNA-binding domain that can specifically bind an AT-rich DNA sequence known to be recognized by a SNF/SWI complex at the beta-globin locus. Second, the C-terminus of the protein can stimulate glucocorticoid receptor-dependent transcriptional activation. It is thought that the protein encoded by this gene confers specificity to the SNF/SWI complex and may recruit the complex to its targets through either protein-DNA or protein-protein interactions. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Genes regulated by ARID1A

Genes likely regulated by ARID1A through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to ARID1A knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.

TFs regulating ARID1A 0 TFs

Transcription factors with Perturb-seq knockdown data for ARID1A. The Binding column indicates whether any binding evidence exists for this TF–gene pair (ChIP-seq or motif footprint peaks). The Mean coef is the average Perturb-seq regression coefficient across active gRNAs (positive = ARID1A upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.

Elements linked to ARID1A

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of ARID1A, linked by TSS proximity or chromatin conformation (Multiome / HiCAR). Each element overlaps at least one TF ChIP-seq binding site — the TFs column shows how many distinct TFs bind that element.
