Alternating rise and fall of SCF - NIPA levels act as switch regulating cell division

...osis (G2 and M phases, respectively). But when it sheds the attached phosphate molecule, NIPA binds to SCF to form SCFNIPA. The addition of NIPA makes SCF specifically target cyclin B1, sending that molecule to the proteasome, the cell's protein-degradation machine. This degradation of cyclin B1 occurs d...
