    ..Since the binding of 14-3-3 proteins to Yak1 coincides with PKA activity, such regulatory mechanisms might allow cytoplasmic retention of an inactive form of Yak1 under high glucose conditions. ..

    ..Taken together, these results place Rim15p immediately downstream and under negative control of cAPK and define a positive regulatory role of Rim15p for entry into both meiosis and stationary phase. ..
