Function
Plays a role in mitotic cell cycle progression and is involved in kinetochore assembly and mitotic sister chromatid cohesion. Probably through its association with CBX5 plays a role in mitotic chromosome segregation by regulating aurora kinase B/AURKB activation and AURKB and CBX5 dissociation from chromosome arms.
POGZ is required for the correct activation and dissociation of Aurora B kinase from chromosome arms during M phase. These results reveal POGZ as an essential protein that links HP1alpha dissociation with Aurora B kinase activation during mitosis.
POGZ was found to bind to HP1alpha through a zinc-finger-like motif. Binding by POGZ, mediated through its zinc-finger-like motif, competed with PxVxL proteins and destabilized the HP1alpha-chromatin interaction.
