The amino acids preceding the identified peptide are indicated (site). The underlined Asp in the identified peptide for LSm3 indicates the processing site validated by detection of an intermally located α-N-acetylated peptide. In Tables 2 and 3, only peptides with corresponding parent proteins with functions related to mRNA-binding/processing and/or protein synthesis are shown.
