The following information accompanied stocks donated to the Bloomington Stock Center by Sergey Sinenko and Sally Kornbluth, Duke University Medical Center. Two UAS constructs for Nc (Dronc; FBgn0026404) were used in the studies described in Yang et al. 2010 (FBrf0211843). One construct expresses FLAG-tagged wild type Nc (P{UAS-Nc.FLAG}; FBtp0071416) and the other expresses a FLAG-tagged S130A variant Nc protein (P{UAS-Nc.S130A.FLAG}, FBtp0069992). No UAS-Nc constructs lacking FLAG sequences were used. P{UAS-Nc.FLAG}2 and P{UAS-Nc.S130A.FLAG}2 are second chromosome insertions. P{UAS-Nc.FLAG}9.3.2 and P{UAS-Nc.S130A.FLAG}10.1.2 are third chromosome insertions
