    Summary
    Enables aldo-keto reductase (NADPH) activity; potassium channel regulator activity; and transmembrane transporter binding activity. Involved in several processes, including NADPH oxidation; myoblast differentiation; and regulation of protein localization to cell surface. Located in several cellular components, including axon; cytoplasmic side of plasma membrane; and microtubule. Part of potassium channel complex. Is active in glutamatergic synapse and postsynaptic density membrane. Orthologous to human KCNAB2 (potassium voltage-gated channel subfamily A regulatory beta subunit 2).

    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.
