Source was S2R+ cell line; bait produced from tagged transfected construct; prey produced from transfected construct.

hid-Myc localizes to mitochondria while Diap1-mCherry is broadly distributed. Coexpression of hid-Myc and Diap1-mCherry results in Diap1-mCherry localization to mitochondria.

Prey identification based on comigration of the far western band with band detected by anti-W western blot.

The start Methionine codon of W is not trimmed in Cdk7 and thus does not bind to th.

Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey derived from mutant or wild-type larval imaginal disc and brain extract.
