ARB2A
ARB2 cotranscriptional regulator A | DKFZP564D172, Toupee, C5orf21, FAM172A

Predicted to contribute to siRNA binding activity. Predicted to be involved in neural crest cell development; regulation of alternative mRNA splicing, via spliceosome; and regulatory ncRNA-mediated heterochromatin formation. Located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Jul 2025]

ARB2A — as a Regulated Gene

TFs regulating ARB2A 0 TFs

Transcription factors with Perturb-seq knockdown data for ARB2A. 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 = ARB2A 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 ARB2A

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of ARB2A, 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.
