UASt regulatory sequences drive expression of the "camgaroo-2" calcium indicator. This protein contains a split citrine fluorophore which has a calmodulin calcium binding domain inserted in it.
Only very small changes in fluorescence have been detected when robust neural activity is induced in the larval neuromuscular junction of animals expressing Avic\GFPcamgaroo2.Scer\UAS.cRa.
