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). dgt2 binds to microtubules in vitro (PubMed:19289792). Component of the augmin complex composed of dgt2, dgt3, dgt4, dgt5, dgt6, msd1, msd5 and wac (PubMed:18443220, PubMed:19289792). The complex interacts directly or indirectly with microtubules and is required for centrosome-independent generation of spindle microtubules (PubMed:18443220). dgt2 interacts directly with wac (via coiled coil) (PubMed:19289792). Stably associates with the polar regions of some acentrosomal meiotic spindles in contrast to the uniform staining observed over mitotic spindles in syncytial embryos (PubMed:19289792, PubMed:23785300). In adult females, detected only in the abdomen with no expression in the head or thorax (at protein level). Expressed at high levels in early embryos but at low levels in larva, pupa and adult (at protein level). The name 'dim gamma-tubulin 2' derives from the decreased gamma-tubulin staining of the spindle pole seen following RNAi-mediated knockdown of dgt2 in S2 cells.
