alpha- and beta-tubulin are fundamental components of the eukaryotic cytoskeleton and cell division machinery. While overall tubulin expression is carefully controlled, most eukaryotes express multiple tubulin genes in specific regulatory or developmental contexts. The genomes of the human parasites Trypanosoma brucei and Leishmania major reveal that these unicellular kinetoplastids possess arrays of tandem-duplicated tubulin genes, but with differences in organisation. While L. major possesses monotypic alpha and beta arrays in trans, an array of alternating alpha- and beta tubulin genes occurs in T. brucei. Polycistronic transcription in these organisms makes the chromosomal arrangement of tubulin genes important with respect to gene expression.
