RAB3A
RAB3A, member RAS oncogene family

Enables GTPase activity and myosin V binding activity. Involved in several processes, including acrosomal vesicle exocytosis; plasma membrane repair; and regulation of plasma membrane repair. Located in perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Jul 2025]

RAB3A — as a Regulated Gene

TFs regulating RAB3A 0 TFs

Transcription factors with Perturb-seq knockdown data for RAB3A. 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 = RAB3A 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 RAB3A

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of RAB3A, 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.
