PPP4R3A
protein phosphatase 4 regulatory subunit 3A | FLFL1, FLJ20707, MSTP033, PP4R3, smk-1, smk1, KIAA2010, SMEK1

Predicted to enable protein phosphatase activator activity. Predicted to be involved in DNA damage response and regulation of double-strand break repair. Predicted to act upstream of or within positive regulation of gluconeogenesis and protein dephosphorylation. Located in cytosol and nuclear speck.

PPP4R3A — as a Regulated Gene

TFs regulating PPP4R3A 0 TFs

Transcription factors with Perturb-seq knockdown data for PPP4R3A. 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 = PPP4R3A 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 PPP4R3A

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PPP4R3A, 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.
