PPP1R1B
protein phosphatase 1 regulatory inhibitor subunit 1B | DARPP-32, FLJ20940

This gene encodes a bifunctional signal transduction molecule. Dopaminergic and glutamatergic receptor stimulation regulates its phosphorylation and function as a kinase or phosphatase inhibitor. As a target for dopamine, this gene may serve as a therapeutic target for neurologic and psychiatric disorders. Multiple transcript variants encoding different isoforms have been found for this gene.

PPP1R1B — as a Regulated Gene

TFs regulating PPP1R1B 0 TFs

Transcription factors with Perturb-seq knockdown data for PPP1R1B. 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 = PPP1R1B 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 PPP1R1B

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PPP1R1B, 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.
