Protein interactions are being studied by researchers across the globe. This book presents the interaction between proteins and other biomolecules, which is crucial to all features of biological procedures such as cell growth and differentiation. Hence, examination and modulation of protein interactions are of vital importance, as it not only discloses the mechanism governing cellular movement, but also leads to possible agents for the treatment of a broad range of disorders. The purpose of this book is to emphasize on some of the most recent advances in the study of protein interactions, along with modulation of protein interactions, improvements in systematic methods, etc. It presents diverse approaches for the study of vital protein interactions. This book demonstrates the significance and the opportunities for further exploration of protein interactions.
