UASt regulates expression of amino acids 1-657, corresponding to Lasp-PB, and tagged at the N-terminus with Tag:FLAG and Tag:polyHis.
Scer\GAL4Mef2.PR-mediated expression of LaspL.Scer\UAS.T:Zzzz\FLAG,T:Zzzz\His6 rescues the sarcomere length and thin filament length phenotypes seen in Lasp1 indirect flight muscles, and also rescues the reduced flight ability of Lasp1 flies.
