PPP1R15A
protein phosphatase 1 regulatory subunit 15A | GADD34

This gene is a member of a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. The induction of this gene by ionizing radiation occurs in certain cell lines regardless of p53 status, and its protein response is correlated with apoptosis following ionizing radiation.

PPP1R15A — as a Regulated Gene

TFs regulating PPP1R15A 0 TFs

Transcription factors with Perturb-seq knockdown data for PPP1R15A. 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 = PPP1R15A 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 PPP1R15A

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PPP1R15A, 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.
