Blast searches identified TPX2 motifs in the protein of various animals and plants, but not in insects, worms or fungi. All researched species that were used to make a relationship tree in Supplemental Figure 2 are shown.
SUPPLEMENTAL FIGURE 2 ONLINE Phylogram of Eukaryote TPX2 Signatures. The relationship tree was constructed on both At TPX2 signature sequences using the Neighbor Joining method and Poisson distance correction. All land plants, including the moss Physcomitrella, possess two copies of the TPX2 signature, suggesting that the duplication occurred before land plant speciation. The TPX2 signature found in vertebrates is more closely related to the second plant signature than to the first one. Interestingly, evolution is quite well respected despite the short length of the signature. Number 1 and 2 refer to the signature positions from N- to C-terminus of TPX2 found in plant species.

Shown are the amino acid sequence alignment of with the crystallographic partial sequence of Hs Aurora A (; top) and the alignment of At TPX2 with the two crystallographic sequences of Hs TPX2 that interact with HsAurora A in the crystal (bottom). The 38 amino acids from human Aurora A indicated by triangles (!, colored according to Fig. 2A) are involved in the interaction with Hs TPX2 and show a variation of their accessible surface when calculated with or without the presence of TPX2. The full length sequence, which may have conserved this function, shows 74% identity and 95% similarity to the human Aurora A sequence.
SUPPLEMENTAL FIGURE 4 ONLINE At TPX2 Localization during Cell Division in Immunolabeled BY-2 cells. (A-H). Endogenous TPX2 (Top), microtubule (middle) and dapi (bottom) staining of cycling cells. TPX2 localization is intranuclear in late G2 (A) and perinuclear in early prophase (B). In late prophase (C) it forms two polar crescents outside of the nucleus. After NEB the spindle becomes labeled (D, E). The polar labeling progressively disappears during anaphase-telophase transition (F-H).
SUPPLEMENTAL FIGURE 5 ONLINE Dynamics of At TPX2 during Cell Division. GFP-At TPX2 fluorescence intensity graph of various BY-2 cell parts during prophase, mitosis and cytokinesis. The nuclear fluorescence is quickly reduced before NEB. The peak at the onset of metaphase is due to the intense labeling of the first microtubule bundles in the plain of focus (see also Figure 3 K at T=3 ). Thereafter, the protein becomes distributed over many newly polymerized microtubules. At the end of anaphase the protein is focused to the shortening kinetochore fibers and is then clearly degraded. All fluorescence intensities were measured as the mean pixel intensities in 50 x 50 pixel boxes of the cell in movie S3, except the nuclear envelope measurements, which were based on a 15 x 15 pixel box. All data were corrected to the background intensity.
SUPPLEMENTAL FIGURE 6 ONLINE Microinjection of TRITC-dextran. As a control, TRITC conjugated dextran (160 kda) was microinjected in a Tradescantia virginiana stamen hair cell during late prophase. The inert polysaccharide distributes throughout the cytoplasmic volume of the cell, but is excluded from the nucleus and the vacuole. Just before NEB (35 to 45 min after injection) a fluorescent halo becomes visible around the nucleus. This coincides with the (organelles excluding) pro-spindle that is formed at that time. The dextran is again excluded from the reforming nucleus during telophase due to the restricted accessible volume between the decondensing chromosomes. Needle concentration was 0.5 mg/ml, time in minutes after injection and the bar is 20!m.
