BAIT

CTF19

MCM18, L000003420, YPL018W
Outer kinetochore protein, needed for accurate chromosome segregation; component of the kinetochore sub-complex COMA (Ctf19p, Okp1p, Mcm21p, Ame1p) that functions as a platform for kinetochore assembly; required for the spindle assembly checkpoint; orthologous to human centromere constitutive-associated network (CCAN) subunit CENP-P and fission yeast fta2
Saccharomyces cerevisiae (S288c)
PREY

CEP3

CBF3, CSL1, CBF3B, L000000312, L000000222, YMR168C
Essential kinetochore protein; component of the CBF3 complex that binds the CDEIII region of the centromere; contains an N-terminal Zn2Cys6 type zinc finger domain, a C-terminal acidic domain, and a putative coiled coil dimerization domain

A putative protein complex consisting of Ctf19, Mcm21, and Okp1 represents a missing link in the budding yeast kinetochore.

Ortiz J, Stemmann O, Rank S, Lechner J

We have established a one-hybrid screen that allows the in vivo localization of proteins at a functional Saccharomyces cerevisiae centromere. Applying this screen we have identified three proteins-Ctf19, Mcm21, and the product of an unspecified open reading frame that we named Okp1-as components of the budding yeast centromere. Ctf19, Mcm21, and Okp1 most likely form a protein complex that links ... [more]
