MIXL1 Transcription Factor
Mix paired-like homeobox | MILD1, MIXL

Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and sequence-specific double-stranded DNA binding activity. Predicted to be involved in several processes, including endodermal cell differentiation; negative regulation of hematopoietic progenitor cell differentiation; and positive regulation of mesoderm development. Predicted to act upstream of or within cell migration involved in gastrulation and hemopoiesis. Located in nucleoplasm. [provided by Alliance of Genome Resources, Jul 2025]

Genes regulated by MIXL1

Genes likely regulated by MIXL1 through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to MIXL1 knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.

Regulatory Elements bound by the TF

Open chromatin elements (ATAC-seq) where MIXL1 has ChIP-seq or motif footprint binding evidence and which are linked to at least one target gene region.

MIXL1 — as a Regulated Gene

TFs regulating MIXL1 0 TFs

Transcription factors with Perturb-seq knockdown data for MIXL1. 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 = MIXL1 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 MIXL1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of MIXL1, 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.
