Chromosome 17: neXt-MP50 C-HPP Challenge Completed

The C-HPP Team for Chromosome 17 has documented meeting the neXt-MP50 Missing Protein Challenge. Protein-level PE1 evidence including MS and protein-protein interaction data from the global proteomics community has reduced the number of PE2,3,4 proteins coded on Chromosome 17 by 50 since the 2016 baseline in neXtProt. As a follow-up to our analysis and prioritization of Chr 17 missing proteins last year, we describe what predictions and guidance were successful in this update and we explain the dynamics of a net reduction of PE2,3,4 Missing Proteins. This analysis can serve as a guide for other C-HPP chromosome teams seeking high-quality evidence for the 2129 remaining missing proteins.
