1 The p27(Kip1) -ubiquitination activity was higher at the G1/S boundary than during the G0/G1 phase, and p27(Kip1) ubiquitination was reduced significantly when the lysine residues at positions 134, 153, and 165 were replaced by arginine, suggesting that these lysine residues are the targets for Ub conjugation.
