ras2 encodes a member of the Ras family of GTP-binding proteins. (A) Alignment showing homology of Ras2 to other fungal Ras proteins. Identical residues are indicated by white letters on black, and similar amino acids are highlighted with a grey background. Sequence alignment was performed with ClustalW (50) and presented with Boxshade 3.21. The proteins used for comparison are Neurospora crassa NC-Ras2, Cryptococcus neoformans Ras2, Aspergillus fumigatus Ras, Candida albicans Ras1, Saccharomyces cerevisiae Ras2, and Schizosaccharomyces pombe Ras1.
