FunctionFunction

[IML3_YEAST] 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.^[1] ^[2] [CHL4_YEAST] 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.^[3]
