Ndc10 component of the yeast centromere-binding factor 3
Ndc10 is a multidomain protein conserved in Saccharomycotina that interacts with kinetochore components. This model characterizes the majority of the protein; some family members may have an additional C-terminal domain that is homologous to transcriptional activators (GCR1_C). Ndc10 is part of the centromere-binding factor 3 (CBF3) complex in budding yeast. The CBF3 complex contains four essential proteins, Ndc10, Cep3, Ctf13, and Skp1. CBF3/Ndc10 is essential for the recruitment of the centromeric nucleosome and formation of the kinetochore. The Kinetochore is the large, multiprotein assembly that serves to connect condensed sister chromatids to the mitotic spindle. Ndc10 forms a dimer and it has non-sequence-specific DNA binding activity via the DNA backbone. Ndc10 also plays an important role in the coordination of cell division. It has been noted that the protein bears resemblance to the tyrosine recombinases (type IB topoisomerase/lambda-integrase).
