Recent technical advances in identifying protein-protein interactions (PPIs) have generated the genomic-wide interaction data, collectively collectively referred to as the interactome. These interaction data give an insight into the underlying mechanisms of biological processes. However, the PPI data determined by experimental and computational methods include an extremely large number of false...

Abstract In the past decade, automatisation has led to an immense increase of data in biology. Next generation sequencing techniques will produce a vast amount of sequences across all species in the coming years. In many cases, identifying the function and biological role of a protein from its sequence can be a complicated and time-intensive task. The identification of a protein’s interaction p...

Protein-protein interaction (PPI) extraction has been an important research topic in bio-text mining area, since the PPI information is critical for understanding biological processes. However, there are very few open systems available on the Web and most of the systems focus on keyword searching based on predefined PPIs. PIE (Protein Interaction information Extraction system) is a configurable...

This chapter introduces evolutionary analyses of protein interaction networks and of proteins as components of the networks. The authors show relationships between proteins in the networks and their evolutionary rates. For understanding protein-protein interaction (PPI) divergence, duplicated genes are often compared because they are derived from a common ancestral gene. In order to reveal evol...

The simplicity and sensitivity of the bimolecular fluorescence complementation (BiFC) assay make it a powerful tool to investigate protein-protein interactions (PPIs) in living cells. However, non-specific association of the fluorescent protein fragments in a BiFC system can complicate evaluation of PPIs. Here, we introduced a bicistronic expression vector, pBudCE4.1, into an mLumin-based BiFC ...

We have studied the changes in protein-protein interaction network of 38 different tissues of the human body. 123 gene expression samples from these tissues were used to construct human protein-protein interaction network. This network is then pruned using the gene expression samples of each tissue to construct different protein-protein interaction networks corresponding to different studied ti...

Protein-protein interactions (PPIs) can be considered as a vast class of therapeutic targets. PPIs play critical roles in all biological functions and are often dysregulated in disease. Despite their functional role both inside and outside the cell, over the past decades PPIs have been neglected as undruggable targets. This was in part due to the fact that PPI interfaces are generally flat and ...

MASP-2, mannose-binding protein-associated serine protease 2, is a key enzyme in the lectin pathway of complement activation. Hyperactivation this protein by human coronaviruses SARS-CoV, MERS-CoV and SARS-CoV-2 has been found to contribute aberrant activation patients, leading aggravated lung injury with potentially fatal consequences. This hyperactivation triggered lungs through conserved, di...
