CENP-C_C is a C-terminal family of fungal and eukaryote proteins necessary for centromere formation. CENP-C is the inner-kinetochore centromere (CEN) binding protein. In the budding-yeast, Mif2, the yeast homolog, binds in the CDEIII region of the centromere, and has been shown to recruit a substantial subset of all inner and outer kinetochore proteins. Mif2 adopts a cupin fold and is extremely similar both in polypeptide chain conformation and in dimer geometry to the dimerization domain of a bacterial transcription factor. The Mif2 dimer appears to be part of an enhanceosome-like structure that nucleates kinetochore assembly in budding yeast. This C-terminal domain is the region via which CENP-C localizes to centromeres throughout the cell cycle 2,3].
