Mmd and GluCl form a complex. Immunoprecipitation experiment. (Left) Extracts from fly heads carrying smGFP-smV5-tagged GluCl and smGFP-smV5-tagged Rdl probed with anti-V5 and anti-Mmd antibodies. (Right) A nanobody against GFP was used to pull down tagged GluCl or tagged Rdl and probed on blots as indicated. GluCl forms a complex with predominantly one form of Mmd. Asterisk, weak band co-precipitating with tagged Rdl.
