The YSK1-related kinase MST4 is Golgi apparatus localized. (A) Full-length YSK1, MST3, and MST4 were tested against empty vector (control), full-length GM130, GM1301-271, and golgin45 for the ability to grow on selective medium (QDO), compared with nonselective medium (−LW) in the yeast two-hybrid system. Lighter colony color on QDO is an indicator of a strong signal. (B) His-tagged MST4 was incubated with GST-tagged fragments of rat GM130, golgin45, or GST and recovered on glutathione-agarose. Recovered complexes were analyzed by Western blotting. (C and D) HeLa cells transfected with myc-tagged MST3 and MST4 constructs for 18 h were costained with the 9E10 mAb to the myc epitope (green) and a sheep antibody to GM130 (red). Bar, 10 μm.
