Effects of BuGZ phase transition and binding to AurA on kinase activity. (A) Purified xAurA (cleaved from mCherry-xAurA) was incubated from purified xBuGZ (cleaved from YFP-xBuGZ) and MBP to assay AurA kinase activity in vitro. CBB, Coomassie Brilliant blue. (B) XEE was mock depleted or depleted (dep) with BuGZ antibody, and the BuGZ-depleted XEE was supplemented with the indicated purified proteins followed by xAurA immunoprecipitation and Western blotting analyses. r IgG, rabbit polyclonal IgG.
