The primary targets of the C-HPP are the so-called “missing proteins” that have not yet been identified by mass spectrometry nor detected by antibodies. An important aspect of the C-HPP work is to define which proteins have already been characterized, to focus on those that have yet to be detected. To help C-HPP in this task, neXtProt captures evidence for the existence of each protein based on criteria established by

UniProtKB/Swiss-Prot in 2007. Five levels of evidence have been defined: (1) evidence at protein level (e.g., identification by mass spectrometry, detection by antibodies, sequence by Edman degradation, or tridimensional structure resolved), (2) evidence at transcript level (e.g., ESTs or full length mRNA), (3) inferred by homology

(strong sequence similarity to known proteins in related species), (4) predicted and (5) uncertain (e.g., dubious sequences that are likely the products of erroneous translations of pseudogenes)

Strategies to Find Missing Proteins

Unusual tissues and cell types: olfactory epithelium, specific brain regions, testis, placenta, oviduct, lung

Development stage: embryo, fetus

Protein families with high homology: keratins, GPCRs, immunoglobulins, histocompatibility antigens—greater sequence coverage and accuracy, variety of methods

Low/very low abundance, high turnover proteins: transcription factors—greater sensitivity; unfavorable physico-chemical properties: hydrophobic, basic, few tryptic sites

Examine RNA-Seq data for evidence of gene expression and mRNA translation (RNC-mRNA)
