Summary
Predicted to enable several functions, including NADPH binding activity; potassium channel regulator activity; and transmembrane transporter binding activity. Acts upstream of or within learning or memory and regulation of potassium ion transmembrane transporter activity. Predicted to be located in several cellular components, including axon; dendrite; and perikaryon. Predicted to be part of voltage-gated potassium channel complex. Predicted to be active in juxtaparanode region of axon. Predicted to be extrinsic component of cytoplasmic side of plasma membrane. Is expressed in brain; heart; reproductive system; and urinary system. Human ortholog(s) of this gene implicated in temporal lobe epilepsy. Orthologous to human KCNAB1 (potassium voltage-gated channel subfamily A regulatory beta subunit 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
