CTBP1 Transcription Factor
C-terminal binding protein 1 | BARS

This gene encodes a protein that binds to the C-terminus of adenovirus E1A proteins. This phosphoprotein is a transcriptional repressor and may play a role during cellular proliferation. This protein and the product of a second closely related gene, CTBP2, can dimerize. Both proteins can also interact with a polycomb group protein complex which participates in regulation of gene expression during development. Alternative splicing of transcripts from this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

Genes regulated by CTBP1

Genes likely regulated by CTBP1 through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to CTBP1 knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.

Regulatory Elements bound by the TF

Open chromatin elements (ATAC-seq) where CTBP1 has ChIP-seq or motif footprint binding evidence and which are linked to at least one target gene region.

CTBP1 — as a Regulated Gene

TFs regulating CTBP1 0 TFs

Transcription factors with Perturb-seq knockdown data for CTBP1. 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 = CTBP1 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 CTBP1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of CTBP1, 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.
