KCNJ5
potassium inwardly rectifying channel subfamily J member 5 | CIR, GIRK4, KATP1, Kir3.4, LQT13

This gene encodes an integral membrane protein which belongs to one of seven subfamilies of inward-rectifier potassium channel proteins called potassium channel subfamily J. The encoded protein is a subunit of the potassium channel which is homotetrameric. It is controlled by G-proteins and has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Naturally occurring mutations in this gene are associated with aldosterone-producing adenomas. [provided by RefSeq, Aug 2017]

KCNJ5 — as a Regulated Gene

TFs regulating KCNJ5 0 TFs

Transcription factors with Perturb-seq knockdown data for KCNJ5. 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 = KCNJ5 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 KCNJ5

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of KCNJ5, 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.
