Slmb is required for oocyte polarisation. (A,B) Kinesin-β-galactosidase (Kin-β-gal) visualised with an antibody against β-gal. Kin-β-gal accumulates at the posterior in wild-type (A) but is diffusely localised to the centre of slmb9H4-17 germline clone oocytes (B). (C,D) Microtubule organisation in wild-type (C) and slmb9H4-17 (D) stage 9 egg chambers visualised with Tau-GFP. (E,F) Egg chambers expressing matα4:GFP-Par-1N1S. GFP-Par-1 forms a posterior crescent in wild-type oocytes (E) but fails to localise to the posterior of most slmb9H4-17 germline clone oocytes (F). (G,H) Par-1-GFP (expressed from a protein trap insertion in the endogenous par-1 locus) forms a posterior crescent in wild-type oocytes (G) but is usually absent from the posterior of hs-Slmb, slmb8/slmb9H4-17 oocytes (H).
