General annotation (Comments)

Function	Acts as a component of the centromere DNA-binding protein complex CBF3, which is essential for chromosome segregation and movement of centromeres along microtubules. CBF3 is required for the recruitment of other kinetochore complexes to CEN DNA. It plays a role in the attachment of chromosomes to the spindle and binds selectively to a highly conserved DNA sequence called CDEIII, found in centromers and in several promoters.
Subunit structure	Component of the CBF3 copmplex, which is formed of CBF3A/CBF2, CBF3B/CEP3, CBF3C/CTF13 and CBF3D. CBF2 strongly interacts with BIR1. Interacts with the central kinetochore protein CTF19. Ref.4 Ref.7
Subcellular location	Nucleus. Centromere. Cytoplasm › cytoskeleton › spindle pole body. Note: Spindle midzone during anaphase B. Ref.5
Miscellaneous	Present with 1350 molecules/cell in log phase SD medium. Ref.6
