In 2002, the base sequence of the human genome was decoded. This breakthrough has revealed that the number of human genes is only around 22,000. This was followed by progress in research targetting proteins in the field of life science, producing significant achievements, but there remains a question as to whether identifying proteins will explain all human physiological functions.
Dr. Hisashi Naramitsu, director of the Research Center for Medical Glycoscience (RCMG) at the national Institute of Advanced Industrial Science and Technology (AIST) is a poineer in glycoscience. In 1985 he became the first to discover a gene that produces glycosyltransferase, or an enzyme that transfers a sugar to a carbohydrate chain and extends it, while researching at the National Institutes of Science (NIH) in the US.
