Quick Reference

A Drosophila gene that encodes a potassium channel (Kv1.1). Related genes shab, shal, and shaw are known in flies and humans and encode homologous potassium channels. The mutation is so called because the fly's legs shake under ether anaesthesia and in humans mutations lead to episodic ataxia/*myokymia syndrome (episodic ataxia type 1).
