HMG20B — as a Regulated Gene

TFs regulating HMG20B 0 TFs

Transcription factors with Perturb-seq knockdown data for HMG20B. 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 = HMG20B 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 HMG20B

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of HMG20B, 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.
