Protein
Inner kinetochore subunit CNN1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Component of the kinetochore, a multiprotein complex that assembles on centromeric DNA and attaches chromosomes to spindle microtubules, mediating chromosome segregation and sister chromatid segregation during meiosis and mitosis. Component of the inner kinetochore constitutive centromere-associated network (CCAN), which serves as a structural platform for outer kinetochore assembly (PubMed:22561346). CNN1 is important for the recruitment of the outer kinetochore Ndc80 complex (PubMed:23334295).
Similarity
Belongs to the CENP-T/CNN1 family.
