ASTE1
asteroid structure-specific endonuclease 1 | HT001

Enables 3' overhang single-stranded DNA endodeoxyribonuclease activity. Involved in double-strand break repair via homologous recombination and double-strand break repair via nonhomologous end joining. Implicated in Lynch syndrome and mismatch repair cancer syndrome.

ASTE1 — as a Regulated Gene

TFs regulating ASTE1 0 TFs

Transcription factors with Perturb-seq knockdown data for ASTE1. 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 = ASTE1 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 ASTE1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of ASTE1, 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.
