INCENP
Chromosomal passengers are proteins that move from centromeres to the spindle midzone during mitosis. Recent experiments show that the passengers inner centromere protein (INCENP) and aurora-B kinase are in a macromolecular complex that might also contain a third passenger, survivin. The chromosomal passenger complex functions throughout mitosis in chromosome condensation and segregation, and at the end of mitosis, in the completion of cytokinesis.
