Kcnq3 - potassium voltage-gated channel subfamily Q member 3

Enables several functions, including calmodulin binding activity; enzyme binding activity; and transmembrane transporter binding activity. Involved in cellular response to ammonium ion; nervous system development; and potassium ion transmembrane transport. Located in several cellular components, including axon initial segment; membrane raft; and neuronal cell body. Is integral component of plasma membrane. Part of voltage-gated potassium channel complex. Human ortholog(s) of this gene implicated in autistic disorder and benign neonatal seizures. Orthologous to human KCNQ3 (potassium voltage-gated channel subfamily Q member 3). [provided by Alliance of Genome Resources, Apr 2022]
