UniProtKB accession:  P43618

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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).
