Function
- tumor suppressor involved in maintenance of ploidy via
- mitotic progression
- G1 tetraploidy checkpoint.
- negatively regulates G2/M transition; down-regulates CDC2 kinase activity
- regulates actin polymerization; negative modulation of LIMK1
- complexes with CDC2 in early mitosis
- binds phosphorylated ZYX, locazing to the mitotic spindle
Compartment
- localizes to the centrosomes throughout interphase
- migrates to the mitotic spindle during mitosis
