Comments concerning this interaction

This interaction was exclusively detected in "canoe" stage spermatids, and not individualizing spermatids. However, it is not clear if the transgenic constructs were expressed earlier than the "canoe" stage.

(Gärtner et al., 2015)

Source was live adult male testes of transgenic fly line; bait produced from tagged transgenic construct; prey produced from tagged transgenic construct.
