PPP1R9B
protein phosphatase 1 regulatory subunit 9B | SPINO, Spn, PPP1R6, PPP1R9

This gene encodes a scaffold protein that functions as a regulatory subunit of protein phosphatase 1a. Expression of this gene is particularly high in dendritic spines, suggesting that the encoded protein may play a role in receiving signals from the central nervous system. The encoded protein has putative tumor suppressor function and decreased expression has been observed in tumors. [provided by RefSeq, Feb 2014]

PPP1R9B — as a Regulated Gene

TFs regulating PPP1R9B 0 TFs

Transcription factors with Perturb-seq knockdown data for PPP1R9B. 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 = PPP1R9B 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 PPP1R9B

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PPP1R9B, 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.
