Protein
Centromere/kinetochore protein zw10 homolog
Organism
Caenorhabditis elegans
Function
Essential component of the mitotic checkpoint, which prevents cells from prematurely exiting mitosis (PubMed:9298984). Required for the assembly of the dynein-dynactin and mdf-1-mdf-2 complexes onto kinetochores (PubMed:18936247). Its function related to the spindle assembly machinery and kinetochore-microtubule attachments likely depends on its association in the mitotic RZZ complex (PubMed:18936247). The RZZ complex recruits the spindly-like protein spdl-1 to kinetochores (PubMed:18765790, PubMed:18936247). To prevent irregular chromosome segregation, the complex also inhibits the attachment of the kinetochore-associated NDC80 complex to microtubules (PubMed:24231804). The recruitment of spdl-1 to kinetochores relieves this inhibition (PubMed:24231804). Required for embryonic development (PubMed:9298984).
Similarity
Belongs to the ZW10 family.
