Mis12 complex is composed of four subunits, Protein MIS12 homolog, Polyamine-modulated factor 1, Kinetochore-associated protein DSN1 homolog, and Kinetochore-associated protein NSL1 homolog (UniProt: Q9H081, Q6P1K2, Q9H410, Q96IY1, respectively) that are encoded by genes known as MIS12 (Gene ID: 79003), PMF1 (Gene ID: 100527963), DSN1 (Gene ID: 79980), and NSL1 (also known as C1orf48, DC31, DC8, MIS14) (Gene ID: 25936) in human. The MIS12 complex is a protein interaction hub for outer kinetochore assembly. This complex acts as the primary microtubule-binding interface at kinetochores and provides a platform to recruit regulatory proteins. In human Mis12 complex subunits are shown to localize with centromere protein A (CENP-A) at inner kinetochores and internally to Ndc80 at outer kinetochores. Mis12 complex plays an essential role in chromosome segregation in vertebrates and contributes to mitotic kinetochore assembly. Reduced levels of Mis12 complex proteins are shown to result in chromosome alignment defects in both human and chicken cells, but spindle bipolarity is not disturbed. (Ref.: Kline SL et al (2006). J.
