Comments concerning this interaction

sqh coimmunoprecipitates flw (Pp1β9C) but not Pp1-87B.

(Vereshchagina et al., 2004)

Source was adults of transgenic fly line; bait produced from tagged transgenic construct; prey produced from tagged transgenic construct.

(Vereshchagina et al., 2004)

Myc-tagged MYPT-75D was moderately overexpressed in these transgenic flies.
