Source was embryos of wild-type fly line; proteins produced from endogenous genes.

l(1)dd4 and Grip75 coimmunoprecipitate and cosediment as part of the γTuRC (γ-tubulin ring complex).

γ-tubulin-containing complexes were immunoprecipitated and fractionated on a sucrose gradient.

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

l(1)dd4 and Grip75 co-fractionate as part of a Sas-4-containing S-γ-TuRC (γ-tubulin ring) complex.

Sas-4 complexes were immunoprecipitated from "high-speed lysates" depleted of mature centrosomes and different Sas-4-containing complexes were fractionated on a sucrose gradient.
