Alternative Splicing of LYT1 Transcripts in Trypanosoma cruzi

As a result of alternative trans splicing, three distinct LYT1 mRNAs are produced in Trypanosoma cruzi, two encoding the full-length LYT1 protein and the third encoding a truncated LYT1 protein lacking a possible signal sequence. Analysis of the three mRNAs in different developmental forms of the parasite revealed that the alternative processing events were regulated differently during the parasite life cycle.
