This domain is subunit three of the augmin complex found from Drosophila to humans [1]. The HAUS-augmin complex is made up of eight subunits. The augmin complex interacts with gamma-TuRC, and attenuation of this interaction severely impairs spindle MT generation. Furthermore, we provide evidence that human augmin plays critical and non-redundant roles in the kinetochore-MT attachment and also central spindle formation during anaphase in human cells.The HAUS complex is required for mitotic spindle assembly and for maintenance of centrosome integrity [2].
