Clinical Proteomic Tumor Analysis Consortium (CPTAC) Data Portal
The Clinical Proteomic Tumor Analysis Consortium (CPTAC) analyzes cancer biospecimens by mass spectrometry, characterizing and quantifying their constituent proteins, or proteome. Mass spectrometry enables highly specific identification of proteins and proteoforms, accurate relative quantitation of protein abundance in contrasting biospecimens, and the localization of post-translational protein modifications, such as phosphorylation, on a protein’s sequence.-
The CPTAC Data Portal is the centralized repository for the dissemination of proteomic data collected by the Proteome Characterization Centers (PCCs) for the CPTAC program. All data is freely available to the public, subject to the data use guidelines.
