OCCPR: A Leader in Cancer Proteomics and Proteogenomics

The mission of the NCI’s Office of Cancer Clinical Proteomics Research (OCCPR) is to improve prevention, early detection, diagnosis, and treatment of cancer by enhancing the understanding of the molecular mechanisms of cancer, to advance proteome and proteogenome science and technology development through community resources (data and reagents), and to accelerate the translation of molecular findings into the clinic. This is achieved through extramural programs such as the Clinical Proteomic Tumor Analysis Consortium (CPTAC), partnerships with Federal agencies, collaborations with international organizations/institutions, and intramural reference laboratories such as the Antibody Characterization Lab and Clinical Proteomic Characterization Lab.
