As part of the augmin complex, plays a role in centrosome-independent generation of spindle microtubules (PubMed:18443220). The complex is required for mitotic spindle assembly through its involvement in localizing gamma-tubulin to spindle microtubules (PubMed:17412918). dgt6 is required for kinetochore fiber formation, mediating nucleation and/or initial stabilization of chromosome-induced microtubules (PubMed:19836241). Component of the augmin complex composed of dgt2, dgt3, dgt4, dgt5, dgt6, msd1, msd5 and wac (PubMed:18443220, PubMed:19369198). The complex interacts directly or indirectly with microtubules and is required for centrosome-independent generation of spindle microtubules (PubMed:18443220). dgt6 interacts with CENP-meta, gamma-tubulin, msps, Ndc80, Nuf2 and tacc (PubMed:19836241). During mitosis, localizes at aster centers in prophase cells (PubMed:19836241). In prometaphase and metaphase, associates with the entire spindle (PubMed:19836241). During early anaphase, primarily detected on the kinetochore fibers undergoing anaphase shortening (PubMed:19836241). In late anaphase and telophase, becomes enriched at the central spindle but is excluded from its middle region (PubMed:19836241). In interphase cells, displays a uniform distribution (PubMed:19836241). Enriched at spindle poles during meiosis in oocytes (PubMed:23785300). During male meiosis, localizes to kinetochores in a microtubule-independent manner but does not concentrate on spindle microtubules (PubMed:24829288). The name 'dim gamma-tubulin 6' derives from the decreased gamma-tubulin staining of the spindle pole seen following RNAi-mediated knockdown of dgt6 in S2 cells. Belongs to the HAUS6 family.
