Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Component of the central kinetochore, which mediates the attachment of the centromere to the mitotic spindle by forming essential interactions between the microtubule-associated outer kinetochore proteins and the centromere-associated inner kinetochore proteins. Required for establishing bipolar spindle-microtubule attachments and proper chromosome segregation.
Subunit structure	Component of the central kinetochore CTF19 complex, which is composed of at least AME1, CHL4, CTF3, CTF19, IML3, MCM16, MCM21, MCM22, NKP1, NKP2 and OKP1.
Subcellular location	Nucleus. Kinetochore. Note: Associated with kinetochores. Ref.3 Ref.4
Miscellaneous	Present with 1630 molecules/cell in log phase SD medium. Ref.5
