    Summary
    Predicted to enable calcium-activated potassium channel activity; outward rectifier potassium channel activity; and potassium ion leak channel activity. Predicted to be involved in cellular response to pH; potassium ion export across plasma membrane; and stabilization of membrane potential. Predicted to be located in plasma membrane. Predicted to be integral component of plasma membrane. Human ortholog(s) of this gene implicated in migraine with aura. Orthologous to human KCNK18 (potassium two pore domain channel subfamily K member 18). [provided by Alliance of Genome Resources, Apr 2022]

    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.
