BCO2
beta-carotene oxygenase 2 | B-DIOX-II, FLJ34464, BCDO2

This gene encodes an enzyme which oxidizes carotenoids such as beta-carotene during the biosynthesis of vitamin A. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

BCO2 — as a Regulated Gene

TFs regulating BCO2 0 TFs

Transcription factors with Perturb-seq knockdown data for BCO2. 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 = BCO2 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 BCO2

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of BCO2, 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.
