The Chromosome 16 Consortium is integrated in the Human Proteome Project that aims to develop an entire map of the proteins encoded by the human genome following a gene-centric strategy (C-HPP) to make progress in the understanding of human biology in health and disease (B/D-HPP). To do this study four human cell lines were selected, MCF7 epithelial cells, CCD18 colon fibroblasts, Ramos and Jurkat B and T lymphocytes respectively. In particular, this subset includes all the data regarding the MCF7 cell line. 6 laboratories contributed to compile all the reported data.
