Kv1.1 Proteins and Enzymes

Kv1.1 belongs to a (Shaker) subfamily of the pota ium channel family. It is a major constituent of presynaptic A-type channels that modulate synaptic transmi ion in CNS neurons. Kv1.1-containing channels have been shown to be complexed with Lgi1, which is causative for an autosomal dominant form of lateral temporal lobe epilepsy. In the hippocampus Kv1.1 and Lgi1 are coa embled with Kv1.4 and Kv 1 in axonal terminals. Kv1.1 is an abundant Kv subunit in the brain that is found predominantly localized to axons and nerve terminals. Mutations in human Kv1.1 result in the dominant disorder Episodic Ataxia Type 1.
