ERO1A
endoplasmic reticulum oxidoreductase 1 alpha | ERO1-alpha, Ero1alpha, ERO1L

Enables oxidoreductase activity. Involved in cell redox homeostasis and chaperone cofactor-dependent protein refolding. Located in Golgi lumen; endoplasmic reticulum; and extracellular space. [provided by Alliance of Genome Resources, Apr 2025]

ERO1A — as a Regulated Gene

TFs regulating ERO1A 0 TFs

Transcription factors with Perturb-seq knockdown data for ERO1A. 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 = ERO1A 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 ERO1A

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of ERO1A, 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.
