This domain is found in Knl1, a sub-unit of the KMN network, present in Homo sapiens. The KMN network is the core of the outer kinetochore which is responsible for microtubule binding/stabilization and controls the spindle assembly checkpoint. This domain is the second of two RING finger, WD repeat, DEAD-like helicase (RWD) domains. The tandem RWD domains mediate kinetochore targeting of the microtubule-binding subunits by interacting with the Mis12 complex. The Mis12 complex is a KMN sub-complex that tethers directly onto the underlying chromatin layer [1].	Domain
