HMG20A
high mobility group 20A | FLJ10739, HMGX1, HMGXB1

Enables identical protein binding activity. Predicted to be involved in regulation of gene expression. Predicted to act upstream of or within negative regulation of neuron differentiation; negative regulation of protein sumoylation; and negative regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Jul 2025]

HMG20A — as a Regulated Gene

TFs regulating HMG20A 0 TFs

Transcription factors with Perturb-seq knockdown data for HMG20A. 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 = HMG20A 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 HMG20A

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of HMG20A, 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.
