C21orf91 — as a Regulated Gene

TFs regulating C21orf91 0 TFs

Transcription factors with Perturb-seq knockdown data for C21orf91. 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 = C21orf91 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 C21orf91

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of C21orf91, 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.
