Kinetochore-associated protein 1 (KNTC1)

Essential component of the mitotic checkpoint, which prevents cells from exiting mitosis. Required for the assembly of the dynein-dynactin and MAD1-MAD2 complexes on kinetochores (PubMed:11146660, PubMed:11590237, PubMed:15824131).

Its function linked to the spindle assembly machinery is proposed to rely on its association in the mitotic RZZ complex. .
