CPEB3
cytoplasmic polyadenylation element binding protein 3 | KIAA0940

Enables mRNA 3'-UTR binding activity and translation factor activity, RNA binding. Involved in cellular response to amino acid stimulus and regulation of gene expression. Located in several cellular components, including cytosol; midbody; and nucleoplasm. Part of CCR4-NOT complex. [provided by Alliance of Genome Resources, Jul 2025]

CPEB3 — as a Regulated Gene

TFs regulating CPEB3 0 TFs

Transcription factors with Perturb-seq knockdown data for CPEB3. 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 = CPEB3 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 CPEB3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of CPEB3, 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.
