    Summary
    Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and delayed rectifier potassium channel activity. Involved in negative regulation of apoptotic process; potassium ion transport; and response to aldosterone. Predicted to be part of monoatomic ion channel complex. Predicted to be active in plasma membrane. Biomarker of retinal degeneration. Orthologous to human KCNH8 (potassium voltage-gated channel subfamily H member 8).

    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.
