SCX
scleraxis bHLH transcription factor | bHLHa41, bHLHa48, SCXA, SCXB

Enables DNA-binding transcription activator activity, RNA polymerase II-specific and bHLH transcription factor binding activity. Contributes to E-box binding activity. Involved in positive regulation of transcription by RNA polymerase II. Located in nucleus. Part of transcription regulator complex. [provided by Alliance of Genome Resources, Jul 2025]

SCX — as a Regulated Gene

TFs regulating SCX 0 TFs

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

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