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.^[1]
• CENP-A is a component of modified nucleosome replacing hitone H3.^[2]
• CENP-E is a motor protein involved inchromosome movement.^[3]
• CENP-M is involved in the kinetochore assembly.^[4]

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.^[5]

Disease

CENP-A is overexpressed in colon cancer.

Relevance

CENP-B is a potential marker for lung cancer.
