PeptideAtlas and the Chromosome-Centric Human Proteome Project

As part of the HUPO Human Proteome Project (HPP), the Plasma Proteome Project (PPP) aims to provide a summary of ensembl of high quality mass spectrometry evidence for protein detections in human blood plasma. Below is the summary of such proteins by chromosome and by protein evidence (PE) level, as cataloged by neXtProt.
