Summary: Enables several functions, including protein heterodimerization activity; transmembrane transporter binding activity; and voltage-gated potassium channel activity. Involved in several processes, including clustering of voltage-gated potassium channels; positive regulation of secretion by cell; and potassium ion export across plasma membrane. Acts upstream of or within potassium ion transport. Located in several cellular components, including dendrite; lateral plasma membrane; and neuronal cell body membrane. Part of voltage-gated potassium channel complex. Is active in cholinergic synapse and postsynaptic specialization membrane. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 26 and epilepsy. Orthologous to human KCNB1 (potassium voltage-gated channel subfamily B member 1).

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.
