Comments concerning this interaction

Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey produced and labeled by in vitro translation.

(Boube et al., 2014)

MED19 can discriminate between different homeodomains. GST-MED19 pulled down Antp, Dfd, Ubx and Abd-B homeodomain peptides, but not en or hth peptides.
