Abstract excerpt
NIPA is an F-box-like protein that contributes to the timing of mitotic entry. It targets nuclear cyclin B1 for ubiquitination in interphase, whereas in G(2)/M phase, NIPA is inactivated by phosphorylation to allow for cyclin B1 accumulation, a critical event for proper G(2)/M transition. We recently specified three serine residues of NIPA and demonstrated a sequential phosphorylation at G(2)/M, where initial...
