Chromosomal passenger proteins are members of a group of proteins that move from centromeres to the spindle midzone during mitosis. INCENP (Inner Centromere Protein) is a chromosomal passenger protein with an essential role in mitosis and meiosis. It is a complex highly basic multidomain protein that is dynamically translocated from metaphase chromosomes to the spindle midzone during or just prior to anaphase. Some INCENP transfers to the equatorial cortex before formation of the cleavage furrow. Ultimately, it is discarded in the midbody at the completion of cytokinesis. INCENP, in complex with the passenger proteins aurora B kinase and survivin, acts at multiple points during mitosis. Studies in knockout mice established INCENP as essential for mouse development and viability. Loss of INCENP results in chromosome segregation defects and failures in cytokinesis. Targeting of survivin to its centromeric and central spindle locations during mitosis is dependent on INCENP. Direct binding of INCENP to beta tubulin has been demonstrated. Interactions of INCENP with heterochromatin protein HP1Hsa alpha and histone H2A.Z were also reported. INCENP levels are increased in several human cancer lines.
