    Summary
    Predicted to enable calcium-activated potassium channel activity and potassium channel regulator activity. Predicted to be involved in detection of calcium ion; neuronal action potential; and potassium ion transport. Predicted to be located in plasma membrane. Predicted to be part of voltage-gated potassium channel complex. Is expressed in ascending aorta and ductus arteriosus. Orthologous to human KCNMB2 (potassium calcium-activated channel subfamily M regulatory beta subunit 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.
