POLQ
DNA polymerase theta | POLH

Enables several functions, including catalytic activity, acting on DNA; identical protein binding activity; and magnesium ion binding activity. Involved in DNA metabolic process; negative regulation of double-strand break repair via homologous recombination; and protein homooligomerization. Located in Golgi apparatus; cytosol; and nucleoplasm. Is active in mitochondrial nucleoid; nucleus; and site of double-strand break. [provided by Alliance of Genome Resources, Jul 2025]

POLQ — as a Regulated Gene

TFs regulating POLQ 0 TFs

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

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