About the Edition

Advances in high throughput techniques for the generation of protein-protein interactions have produced a wealth of data. Inherent to these techniques is a large amount of false positive results necessitating careful analysis of the data. In order to pursue further analysis of the interaction data without propagating false positive data into subsequent studies it is vital that researchers are able to filter interaction data to retrieve only the high quality records. Taking a subset of curated yeast interactions from BIND, Dip, MINT and IntAct as a high confidence set of interactions we collated a set of features that characterize the interaction. A randomly generated protein interaction subset serves as our low confidence or negative set. We developed a probabilistic framework for assigning confidence to binary protein interactions by training an SVM to deduce the likelihood, or confidence score, of a binary interaction based on its set of features.

David Eisenberg and his research group focus on protein interactions. In their experiments they study the structural basis for conversion of normal proteins to the amyloid state . (source: Nielsen Book Data) Protein-protein interactions (PPIs) are strongly predictive of functional relationships among proteins in virtually all processes that take place in the living cell. Therefore, the comprehensive exploration of interactome networks is one of the major goals in systems biology. This book integrates different approaches from bioinformatics, biochemistry, computational analysis and systems biology to offer the reader a comprehensive global view of the diverse data on protein-protein interactions and protein interaction networks. Quantitative Trait Loci (QTL) analysis of an experimental genetic cross is an ideal approach for mapping the genetic basis of complex traits. QTLs can be mapped at high resolution using high-throughput, whole-genome sequencing of pooled individuals from extremely large recombinant zdorovayaeda-online.top by:
