P{EP} insertion upstream of CG1523. The P{EP} element is oriented such that expression from the element results in overexpression of CG1523.
embryonic/larval salivary gland, with Scer\GAL4fkh.PH
Expression via Scer\GAL4fkh.PH results in a strongly penetrant but variable phenotype in the embryonic salivary gland.
