This gene encodes a protein that specifically binds to a Pit1-binding element of the prolactin (PRL) promoter. This protein may act as a transcriptional regulator and is thought to be involved in some of the developmental abnormalities observed in patients with partial trisomy 2p. This gene overlaps the abhydrolase domain containing 1 (ABHD1) gene on the opposite strand. [provided by RefSeq, Jul 2008]
Modules significantly affected by knockdown. ↑ Up = module upregulated upon KD; ↓ Down = module downregulated upon KD.

Genes likely regulated by PREB through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to PREB knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.
Open chromatin elements (ATAC-seq) where PREB has ChIP-seq or motif footprint binding evidence and which are linked to at least one target gene region.

|---|
Transcription factors with Perturb-seq knockdown data for PREB. 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 = PREB upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.

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