Abstract
Background: NIPA is involved in timing mitotic entry and is inactivated by phosphorylation. The kinase responsible for NIPA phosphorylation at G 2/M is unknown. Results: We show that cell cycle-dependent phosphorylation of NIPA is mediated by ERK2. Conclusion: NIPA is identified as one of the very few ERK2-specific substrates at the G2/M transition. Significance: This demonstrates divergent functions of ERK1 and ERK2 in cell cycle regulation.
