CTF19/YPL018W Summary Help

Standard Name CTF19 1
Systematic Name YPL018W
Alias MCM18
Feature Type ORF, Verified
Description 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 (1, 2, 3, 4, 5)
