The P{EP}eIF-4aEP1011 insertion maps within chic. The insertion is also just upstream of eIF-4a, in the right orientation to drive overexpression of eIF-4a in the presence of a Scer\GAL4 driver.
Expression via Scer\GAL4fkh.PH results in strongly penetrant gland shape/lumen ('shepherd's crook') and positioning ('hook') phenotypes in the embryonic salivary gland.
