TGIF1 Transcription Factor
TGFB induced factor homeobox 1 | HPE4, TGIF

The protein encoded by this gene is a member of the three-amino acid loop extension (TALE) superclass of atypical homeodomains. TALE homeobox proteins are highly conserved transcription regulators. This particular homeodomain binds to a previously characterized retinoid X receptor responsive element from the cellular retinol-binding protein II promoter. In addition to its role in inhibiting 9-cis-retinoic acid-dependent RXR alpha transcription activation of the retinoic acid responsive element, the protein is an active transcriptional co-repressor of SMAD2 and may participate in the transmission of nuclear signals during development and in the adult. Mutations in this gene are associated with holoprosencephaly type 4, which is a structural anomaly of the brain. Alternative splicing has been observed at this locus and multiple splice variants encoding distinct isoforms are described. [provided by RefSeq, Jul 2013]

Genes regulated by TGIF1

Genes likely regulated by TGIF1 through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to TGIF1 knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.

TFs regulating TGIF1 0 TFs

Transcription factors with Perturb-seq knockdown data for TGIF1. 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 = TGIF1 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 TGIF1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of TGIF1, 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.
