TAL1
TAL bHLH transcription factor 1, erythroid differentiation factor | SCL, bHLHa17, TCL5

Enables several functions, including E-box binding activity; RNA polymerase II-specific DNA-binding transcription factor binding activity; and histone deacetylase binding activity. Involved in several processes, including myeloid cell differentiation; positive regulation of cellular component organization; and positive regulation of erythrocyte differentiation. Located in chromatin and nucleoplasm. Part of transcription regulator complex. Implicated in acute lymphoblastic leukemia. [provided by Alliance of Genome Resources, Jul 2025]

Expression (TPM)
TAL1 — as a Regulated Gene

TFs regulating TAL1 0 TFs

Transcription factors with Perturb-seq knockdown data for TAL1. 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 = TAL1 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 TAL1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of TAL1, 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.
