Amino acid replacement: F52A.
UAS regulatory sequences drive expression of mutated CkIIα sequences tagged at the N-terminal with EGFP.
Amino acid replacement: L39A.
lethal - all die during third instar larval stage, with CkIIαLL05896, Scer\GAL4da.G32
CkIIαL39A.F52A.UAS.EGFP/Scer\GAL4da.G32 partially rescues CkIIαLL05896
