This domain is found at the C-terminal region of Nuf2 proteins. This domain was identified as MazG related domain also designated as Designed helical repeat protein 10 (DHR10) [1] that actually adopts a coiled-coil structure [2]. Nuf2 is part of the Ndc80 complex, which binds to the spindle and is required for chromosome segregation and spindle checkpoint activity [3,4].
