Summary: Enables delayed rectifier potassium channel activity; transmembrane transporter binding activity; and voltage-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential. Involved in several processes, including cellular response to nitric oxide; nervous system development; and protein complex oligomerization. Located in several cellular components, including axon; basolateral plasma membrane; and neuronal cell body membrane. Part of voltage-gated potassium channel complex. Is active in GABA-ergic synapse and presynaptic membrane. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 103. Orthologous to human KCNC2 (potassium voltage-gated channel subfamily C member 2). [provided by Alliance of Genome Resources, Dec 2024]

In the absence of potassium ion, significant N-methyl-D-glucamine (NMDG)-positive currents could be recorded from human embryonic kidney cells expressing Kv3.1 or Kv3.2b channels and Kv1.5 Arg487Tyr/Val, but not wild-type channels.

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.
