PITDB is a publicly available database for sharing of results from PIT (proteomics informed by transcriptomics) experiments. PIT  involves the analysis of a given sample by both RNA-seq and proteomic mass spectrometry followed by integration of the acquired data to provide an unprecedented level of information about which genomic elements are being transcribed and translated within a given sample, even if the organism under study does not have an annotated genome. Observed translated genomic elements (TGEs) are BLASTed against reference proteomes using a published workflow  to determine whether they are known proteins, protein variants or novel gene products.
