Characterization of human Dgt6 in HeLa cells. (A) Alignment of N-terminal regions of Dgt6 proteins from D. melanogaster, Xenopus laevis, and Homo sapiens. Identical amino acids are boxed and the similar ones are hatched. (B) Uniform spindle localization of GFP-tagged human Dgt6 in metaphase (green). (C) Dim γ-tubulin and sparse MT phenotypes after RNAi knockdown of hDgt6 in HeLa cells (72 h). (D) Quantitation of γ-tubulin or MT level at centrosomes and spindles. Ratio of spindle and centrosome signal intensity in hDgt6 RNAi cells (γ-tubulin, 0.17 ± 0.02 SEM [n = 14]; MT, 0.46 ± 0.02 SEM [n = 19]) was significantly (P < 0.0005) lower than in control (γ-tubulin, 0.33 ± 0.04 SEM [n = 7]; MT, 0.75 ± 0.02 SEM [n = 15]). γ-tubulin (red) and DNA (blue) were counterstained. Bars, 10 μm.
