CENPF: Proteins and Enzymes

CENPF (Centromere protein F) is required for proper chromosome segregation in mitosis, and has a cell-cycle distribution that is both temporally regulated and diverse in terms of the structural component localization. Specifically, CENPF is a component of the nuclear matrix during the G2 phase of interphase. In late G2, it associates with the kinetochore and maintains this association through early anaphase. Here, CENPF is required for kinetochore function and appears to be the earliest member to interact with the centromere-kinetochore complex. It then localizes to the spindle midzone in late anaphase and to the intracellular bridge in telophase, where the protein is subsequently degraded. Given this diversity of function, CENPF is expected to play an important role in several mitotic events.
