A GFP-tagged Julius seizure (Jus) co-immunoprecipitation identifies a 23-protein complex containing Na+/K+ ATPase subunits ATPalpha and Nervana 3 in Drosophila melanogaster.
- Why it matters: Epileptogenesis is poorly understood, and the jus mutant model offers a way to dissect how specific molecular pathways shape adult seizure susceptibility.
- What they did: Using co-IP baited by GFP-tagged Jus, the authors mapped a 23-associated-protein complex and tested RNAi knockdown of ATPalpha, Nervana 3, and 8 additional complex proteins in jus mutants.
- The result: Knockdown of ATPalpha, Nervana 3, or any of the 8 additional proteins enhanced seizure susceptibility; Jus protection is confined to pupal stages P4–7 and can be rescued by increasing neural activity in jus-expressing neurons during mid-pupal development.
