Fl(2)d and Sxl form protein–protein complexes in wild-type and fl(2)d¹ ovaries. An asterisk indicates an additional band picked up by Fl(2)d antibody in ovarian extract. (A) Fl(2)d-probed Western blot. Lane 1, embryonic extract; lane 2, ovarian extract. (B) Fl(2)d-probed immunoprecipitations from wild-type ovarian extract. Lane 1, ovarian extract; lane 2, Sxl immunoprecipitation; lane 3, Scute immunoprecipitation. (C) Fl(2)d-probed immunoprecipitations from fl(2)d¹ ovarian extract. Lane 1, ovarian extract; lane 2, Sxl immunoprecipitation; lane 3, Scute immunoprecipitation.
