juIs352 [col-19p::GFP::moesin]. GFP::moesin expression labels F-actin by fusing GFP to sequences that encoded the C-terminal end of the sole Drosophila MER homolog, moesin. The F-actin ring (GFP::moesin) is induced upon needle wounding. Reference: Xu S & Chisholm AD. Curr Biol. 2011 Dec 6;21(23):1960-7.
