KCNK1
potassium two pore domain channel subfamily K member 1 | DPK, K2p1.1, TWIK-1

This gene encodes one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. The product of this gene has not been shown to be a functional channel, however, it may require other non-pore-forming proteins for activity. [provided by RefSeq, Jul 2008]

KCNK1 — as a Regulated Gene

TFs regulating KCNK1 0 TFs

Transcription factors with Perturb-seq knockdown data for KCNK1. 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 = KCNK1 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 KCNK1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of KCNK1, 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.
