Young-Ki Paik (Korean: 백영기) is the director of the Yonsei Proteome Research Center in Seoul, Korea.
In 1983, he then moved to Gladstone Institutes, University of California, San Francisco, CA and started his postdoc carrier with John Taylor on molecular cell biology of human apolipoprotein E gene which is involved in transportation of cellular cholesterol from peripheral tissues to liver.
The outcome of his postdoctoral studies was the molecular characterization and transcriptional regulation of human ApoE gene (ε4), which was later found to be involved in the late onset of Alzheimer disease.
Most of work has been done at Yonsei University where he carried out three arms of research, sterol metabolism, C. elegans pheromone, and cancer proteomics.
[12][13] In 2012, Paik and his colleagues at HUPO organized the international consortium of Chromosome-Centric Human Proteome Project (C-HPP) which aims to identify, quantify, and localize expression of at least one representative protein from each of the ~20,000 predicted protein-coding genes in a chromosome-by-chromosome manner.
