Comprehensive annotation of RNA-Seq transcripts. GO annotations reveal the wide range of biological process associated with the G. tigrina predicted proteome. Level 2 categories provide the most general functional annotation, with the largest fraction of proteins assigned to cellular and metabolic processes. The majority of signal transduction related proteins are captured in Level 4 annotations, and Level 6 annotations contain predictions for smaller numbers of proteins implicated in more specialized pathways (e.g. protein modification and DNA metabolism).
