Protein
Centromere DNA-binding protein complex CBF3 subunit A
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
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.
