FUNDAMENTALS OF PROTEIN-PROTEIN INTERACTIONS AND THEIR METHODS OF CHARACTERIZATION
##plugins.themes.academic_pro.article.main##
Abstract
Protein-protein interactions are ubiquitous biological phenomena in all types of organism and play vital roles in various metabolic processes. Therefore, it is very important to understand how protein-protein interactions take place and govern different mechanisms at cellular and molecular levels. Thus, determination of protein-protein interactions is the key in elucidating such mechanisms. In order to provide adequate knowledge and guidance in selecting appropriate methods to determine protein-protein interactions, this article will review basic principles, definitions, terminologies, parameters and classification of protein-protein interactions, obtained either from in silico or laboratory experimental works. Some examples of commonly used biochemical and biophysical methods for characterization of protein-protein interactions were also discussed.
