UASt regulates expression of amino acids 1-657, corresponding to Lasp-PB, but with the LIM domain (amino acids T4-H100) deleted, and tagged at the N-terminus with Tag:FLAG and Tag:polyHis.
Scer\GAL4Mef2.PR-mediated expression of LaspΔLIM.L.Scer\UAS.T:Zzzz\FLAG,T:Zzzz\His6 rescues the sarcomere length, thin filament length, myofibril diameter and flight phenotypes seen in Lasp1 mutants.
