ABSTRACT:
Genomic and cDNA clones corresponding to the tipE gen of Drosophila melanogaster are described. The tipE protein functions in concert with the para gene product, a polypeptide which exhibits similarity to mammalian voltage-dependent sodium channel .alpha. subunits but is not by itself functional. Coexpression of the tipE and para genes in a host cell affords functional cation channels. The invention accordingly provides screening assays for modulators of Drosophila cation channels employing cells expressing both tipE and para polypeptides, useful inter alia to evaluate candidate pesticidal agents.
