Summary: Predicted to enable outward rectifier potassium channel activity and potassium ion leak channel activity. Acts upstream of or within negative regulation of systemic arterial blood pressure and regulation of resting membrane potential. Predicted to be active in plasma membrane. Is expressed in heart; liver left lobe; and liver right lobe. Orthologous to human KCNK6 (potassium two pore domain channel subfamily K member 6). [provided by Alliance of Genome Resources, Dec 2024]

Deletion of Kcnk6 (encoding two-pore domain K(+) channel TWIK2) prevents NLR Family, Pyrin Domain-Containing 3 Protein (NLRP3) inflammasome activation in macrophages and suppressed sepsis-induced lung inflammation. Adoptive transfer of Kcnk6(-/-) macrophages into mouse airways after macrophage depletion also prevents inflammatory lung injury.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
