MutationCi-VSP contains R217Q mutation; super ecliptic pHluorin contains D147A, H148A, Y200V and A227D mutations. These mutations cause depolarization-dependent increase in fluorescence intensity. We replaced residues 71-91 within CiVSD with an amino acid sequence (KSRITSEGEYIPLDQIDINV) from the Kir2.1 channel Golgi-to-plasma membrane trafficking signal. The Kir 2.1 channel ER export signal sequence (FCYENEV) was added to C-terminus of super ecliptic pHluorin.
