NKX2-5
NK2 homeobox 5 | CSX1, NKX2.5, NKX4-1, CSX, NKX2E

This gene encodes a homeobox-containing transcription factor. This transcription factor functions in heart formation and development. Mutations in this gene cause atrial septal defect with atrioventricular conduction defect, and also tetralogy of Fallot, which are both heart malformation diseases. Mutations in this gene can also cause congenital hypothyroidism non-goitrous type 5, a non-autoimmune condition. Alternative splicing results in multiple transcript variants.

NKX2-5 — as a Regulated Gene

TFs regulating NKX2-5 0 TFs

Transcription factors with Perturb-seq knockdown data for NKX2-5. 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 = NKX2-5 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 NKX2-5

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of NKX2-5, 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.
