    Summary
    Predicted to enable calmodulin binding activity and small conductance calcium-activated potassium channel activity. Predicted to be involved in potassium ion transmembrane transport. Predicted to act upstream of or within monoatomic ion transmembrane transport and potassium ion transport. Predicted to be located in membrane. Predicted to be active in neuron projection; neuronal cell body; and plasma membrane. Is expressed in several structures, including heart; nervous system; pectoral fin bud; segmental plate; and tail bud. Orthologous to human KCNN1 (potassium calcium-activated channel subfamily N member 1). [provided by Alliance of Genome Resources, Dec 2024]

    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.
