As part of the augmin complex, plays a role in centrosome-independent generation of spindle microtubules. The complex is required for mitotic spindle assembly through its involvement in localizing gamma-tubulin to spindle microtubules. Component of the augmin complex composed of dgt2, dgt3, dgt4, dgt5, dgt6, msd1, msd5 and wac (PubMed:19369198). The complex interacts directly or indirectly with microtubules and is required for centrosome-independent generation of spindle microtubules.
