RAPGEF3
Rap guanine nucleotide exchange factor 3 | EPAC, bcm910, cAMP-GEFI

Enables guanyl-nucleotide exchange factor activity and protein domain specific binding activity. Involved in several processes, including Rap protein signal transduction; cellular response to cAMP; and regulation of syncytium formation by plasma membrane fusion. Located in several cellular components, including filopodium; lamellipodium; and microvillus. Implicated in nicotine dependence. Biomarker of congestive heart failure.

Expression (TPM)
RAPGEF3 — as a Regulated Gene

TFs regulating RAPGEF3 0 TFs

Transcription factors with Perturb-seq knockdown data for RAPGEF3. 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 = RAPGEF3 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 RAPGEF3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of RAPGEF3, 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.
