Source was embryos of wild-type fly line; bait produced from endogenous gene; prey produced from endogenous gene.

The interaction of Sas-4 with asl is disrupted by the addition of a non-hydrolyzable GTP analog, GMPCPP, to the extract.

The interaction of Sas-4 with asl is increased by the addition of griseofulvin to the extract, a compound that induces hydrolysis of tubulin-bound GTP to GDP.
