Alternatively spliced aminoacyl tRNA synthetase mRNAs (AARS).

Depicted are 600 nucleotides from the 5′ region of six alternatively spliced AARS transcripts. The major spliced site (red triangle) and minor splice site (black triangle) are indicated in tags per million in procyclic forms. The yellow bar indicates the AUG downstream of the minor and major splice sites. The blue box represents the N-terminal mitochondrial targeting signal as determined by MITOPROT. The 2* marks tags, that were only seen in larger procyclic libraries (e.g. Alba1 and 3/4).
