Intractable epilepsies, that is, seizure disorders that do not respond to currently available therapies, are difficult, often tragic, neurological disorders. Na+ channelopathies have been implicated in some intractable epilepsies, including Dravet syndrome, but little progress has been forthcoming in therapeutics. Here we examine a Drosophila model for intractable epilepsy, the Na+ channel gain-of-function mutant parabss1 that resembles Dravet syndrome in some aspects. In particular, we identify second-site mutations that interact with parabss1, seizure enhancers, and seizure suppressors. We describe one seizure-enhancer mutation named charlatan (chn). The chn gene normally encodes an Neuron-Restrictive Silencer Factor/RE1-Silencing Transcription factor transcriptional repressor of neuronal-specific genes. We identify a second-site seizure-suppressor mutation, gilgamesh (gish), that reduces the severity of several seizure-like phenotypes of parabss1/+ heterozygotes. The gish gene normally encodes the Drosophila ortholog of casein kinase CK1g3, a member of the CK1 family of serine-threonine kinases. We suggest that CK1g3 is an unexpected but promising new target for seizure therapeutics.
