Characterization of a Trypanosoma cruzi specific nuclear repeated sequence.
We report the isolation of three different clones from a Trypanosoma cruzi genomic library bearing a common repeated sequence. This sequence is not tandemly repeated, and is dispersed on many chromosomes. All of the T. cruzi strains tested share this element. On the other hand, it is absent from the genome of other Kinetoplastida. The size of this element is about 10-12 kb, and its copy number is 220 in the T. cruzi Dm 28c genome. A transcript homologous to this sequence is detected in epimastigote forms of the parasite.
