By screening of cDNA and genomic libraries of Plasmodium falciparum with a DNA probe derived from the cognate beta-tubulin gene, gene Pf gamma tub has been identified that codes for gamma-tubulin, a newly discovered member of the tubulin superfamily that is indispensible for nuclear division and microtubule assembly [12]. Gene Pf gamma tub is not interrupted by introns and only present as a single-copy in the parasite genome. Its encoded amino acid sequence (452 amino acids; M(r) 50,560) has a 63% similarity to the gamma-tubulins encoded by Aspergillus nidulans, Schizosaccharomyces pombe, Drosophila melanogaster, Xenopus laevis and Homo sapiens. This figure is significantly (approx. 8%) lower than the average identity between the gamma-tubulins of the latter five species suggesting that during evolution the genes have been exposed to different selection pressures. The identity of gamma-tubulin to the Plasmodium falciparum encoded alpha- and beta-tubulins is 30 and 33%, respectively.
