    Summary
    Enables voltage-gated potassium channel activity. Involved in potassium ion transmembrane transport. Located in axon initial segment and plasma membrane. Part of voltage-gated potassium channel complex. Human ortholog(s) of this gene implicated in benign neonatal seizures and developmental and epileptic encephalopathy 7. Orthologous to human KCNQ2 (potassium voltage-gated channel subfamily Q member 2). [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.
