It is my very great pleasure to announce the launch of Protein & Cell.Understanding the cell, the basic unit of life, is a complicated process but is the source for all the key answers pertaining to the life sciences. A sophisticated view of the nature and essence of life requires systematic studies of the whole cell and the cellular components, ranging from small molecules, nucleic acids and carbohydrates to proteins and macromolecular complexes. Starting from the universal genetic cede,as simple as A, C, T and G, twenty standard amino acids are translated and thousands of proteins are assembled. Proteins function in concert with molecules both inside and outside cells. A single cell can represent the entirety of life in the case of bacteria, while differentiated cells form more complicated tissues and organisms. As implied by the title,Protein & Cell intends to promote greater understanding of the cell, the elementary unit of life, via structural and functional studies of its components.
