An international organization aiming to create a database of all human proteins has chosen a project submitted by a Niigata University team that is designed to map out all the proteins in the human kidney and urine as one of its scientific initiatives, sources said Friday.

The project by the team led by Tadashi Yamamoto, professor of structural pathology at the Institute of Nephrology, is the second one from Japan to be adopted by the Human Proteome Organization based in Montreal after the "Human Disease Glycomics" project by an Osaka University team.

About 90 percent of serious kidney disease sufferers requiring dialysis and transplants will eventually fail to urinate because of the loss of glomerular functions responsible for filtering blood.
