About this book

Focusing on protein classification and meta-organization, "Computational Proteomics" describes detailed methods for detecting self-organization in complex biological systems. This book presents the analysis of biological entities and their cellular counterparts and discusses methods for detecting the building blocks of proteins and for prediction and analysis of protein-protein interactions, expression data analysis, and pathway analysis. It also examines protein space and prediction of protein function. This book includes chapters on the analysis of protein-related data types, such as expression, as well as special chapters on Bayesian networks and their application to the protein space.
