    Summary
    Predicted to enable aldo-keto reductase (NADPH) activity; potassium channel regulator activity; and transmembrane transporter binding activity. Involved in neuromuscular process. Acts upstream of or within hematopoietic progenitor cell differentiation. Located in axon terminus; juxtaparanode region of axon; and postsynaptic density. Is active in axon initial segment. Is expressed in several structures, including central nervous system; genitourinary system; hemolymphoid system; intestine; and sensory organ. Used to study chromosome 1p36 deletion syndrome. Orthologous to human KCNAB2 (potassium voltage-gated channel subfamily A 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.
