Figure 4. Drosophila Ca²⁺-activated dBest1 currents are inhibited by a potent CaMKII inhibitor, KN-93.

A) KN-93, (10 µM), reduces current amplitude, whereas its inactive structural analogue, B) KN-92 (10 µM), has no effect on dBest1 currents. C) A very specific peptide inhibitor of CAMKII, myristoylated AIP, also inhibits dBest1 currents. Error bars indicate mean +/− SEM.
