Proteomics is kind of ‘big science’, just like genomics. Whereas genomics looks globally at the underlying DNA sequence of an entire organism, proteomics is the study of the total complement of proteins. There are more proteins than genes as a result of alternative splicing of genes and post-translational modifications such as glycosylation or phosphorylation. Proteomics therefore offers an exhaustive approach to inspecting the inner workings of cells, tissues and organism, and has huge potential for broadening our understanding of the most complex of protein expression, functions and interactions. That is why proteomics has drawn so much attention from researchers in life sciences and has propelled the rapid development of cutting-edge biotechnology in the 21st Century1. In this article, we give a taste of proteomics research in China.
