TMSB4X
thymosin beta 4 X-linked | TB4X, TMSB4

This gene encodes an actin sequestering protein which plays a role in regulation of actin polymerization. The protein is also involved in cell proliferation, migration, and differentiation. This gene escapes X inactivation and has a homolog on chromosome Y. [provided by RefSeq, Jul 2008]

TMSB4X — as a Regulated Gene

TFs regulating TMSB4X 0 TFs

Transcription factors with Perturb-seq knockdown data for TMSB4X. 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 = TMSB4X 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 TMSB4X

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of TMSB4X, 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.
