Fig. 1. Alignment of Bub3 homologues. A Clustal alignment of Bub3 proteins from
Saccharomyces cerevisiae (M64707), Drosophila melanogaster
(AF106679), Homo sapiens (AF047473) and Xenopus laevis
(AB018419/AF119790). Identical residues are shown in black and similar
residues are highlighted in grey. The region against which the peptide
antibodies were raised is underlined.
