Abstract: The Drosophila slowpoke gene encodes a large
conductance calcium-activated potassium channel used
in neurons, muscle, and some epithelial cells. Tissue-
specific transcriptional promoters and alternative mRNA
splicing generate a large array of transcripts. These dis-
tinct transcripts are thought to tailor the properties of the
channel to the requirements of the cell. Presumably, a
single splice variant cannot satisfy the specific needs of
all cell types. To test this, we examined whether a single
slowpoke splice variant was capable of complementing
all slowpoke behavioral phenotypes. Null mutations in
slowpoke cause animals to be semiflightless and to man-
ifest an inducible "sticky-feet" phenotype. The well-char-
acterized slowpoke transcriptional control region was
