Centromere protein

Function Centromere proteins (CENP) X,S,W,T make up the kinetochore structure on chromatids where the spindle fibers attach during cell division to pull the chromatids apart. • CENP-X is a component of the Fanconi Anemia core. • CENP-B facilitates centromere formation. • CENP-A is a component of modified nucleosome replacing hitone H3. • CENP-E is a motor protein involved inchromosome movement. • CENP-M is involved in the kinetochore assembly. Inner centromere protein (INCENP) is a component of the chromosomal passenger complex which regulates mitosis. INCENP are localized at the centromeres during mid-metaphase of the cell cycle.
