"In wild-type embryos, GFP-γ-tubulin localizes to centrosomes during interphase and the amount of centrosomal γ-tubulin increases approximately sixfold as embryos enter mitosis (Fig. 4 B; Hannak et al., 2001). In gip-1(RNAi) embryos (n = 20), GFP-γ-tubulin was either greatly reduced or absent (Fig. 4 B)."
"In wild-type embryos, CeGrip-1 colocalizes with c-tubulin at centrosomes during interphase (unpublished data) and mitosis (Fig. 4 C, left). In gip-1(RNAi) embryos, c-tubulin fails to target to centrosomes (n = 10 embryos; Fig. 4 C, right)"
