Information regarding binding proteins has been comprehensively illustrated in this book. Proteins are important drivers of cellular activities. Different types of proteins along with other agents like DNA, RNA and peptides exercise their functions. The proteins and their binding allies must be known in order to comprehend the mechanism through which they work in the cell and the organism. These protein interactions are important in balancing the cell fates and in the production of various drugs. Stability and translations are monitored when proteins bind with mRNA. Also, they participate in processes like cell survival and apoptosis. Proteolysis or protein breakdown is also a result of their interaction with other proteins. This book is the collection of articles by various experts addressing protein interaction with above mentioned agents. This book caters to the interest of the people who are involved in the study of protein interactions and their consequences.
