Stripped sequence libraries facilitate MS/MS analysis of large proteomes. Sequence libraries stripped of duplicated trypsin fragments give much smaller search spaces for PSM algorithms. The mRNAs from alternative splicing produce proteins with high sequence redundancy, most of which is removed when duplicated trypsin fragments are removed from the proteins of the sequence library. Alternative transcription start sites are shown (*).
