HA-LUBEL 1-872 or LacZ (control) was expressed under the control of Mef2-GAL4, and the progenies were raised at 25°C. The 3IL carcass fillet lysates were subjected to anti-HA immunoprecipitation. To identify potential binding partners, we performed immunoprecipitation-mass spectrometry (IP-MS) of LUBEL1-872.
