CC -!- FUNCTION: Component of the kinetochore, a multiprotein complex that
CC assembles on centromeric DNA and attaches chromosomes to spindle
CC microtubules, mediating chromosome segregation and sister chromatid
CC segregation during meiosis and mitosis. Component of the inner
CC kinetochore constitutive centromere-associated network (CCAN), which
CC serves as a structural platform for outer kinetochore assembly.
CC {ECO:0000269|PubMed:11361335, ECO:0000269|PubMed:15241623}.
CC -!- SUBUNIT: Forms a heterodimer with IML3 (PubMed:12589047,
CC PubMed:24075991). CHL4-IML3 is part of a larger constitutive
CC centromere-associated network (CCAN) (also known as central kinetochore
CC CTF19 complex in yeast), which is composed of at least AME1, CHL4,
CC CNN1, CTF3, CTF19, IML3, MCM16, MCM21, MCM22, MHF1, MHF2, MIF2, NKP1,
CC NKP2, OKP1 and WIP1 (PubMed:12408861, PubMed:22561346). Interacts with
CC CHL4 and CTF19 (PubMed:12589047). {ECO:0000269|PubMed:12408861,
CC ECO:0000269|PubMed:12589047, ECO:0000269|PubMed:22561346,
CC ECO:0000269|PubMed:24075991}.
CC -!- SUBCELLULAR LOCATION: Nucleus. Chromosome, centromere, kinetochore.
CC Note=Associated with kinetochores.
CC -!- MISCELLANEOUS: Present with 125 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the CENP-L/IML3 family. {ECO:0000305}.
