The binding and ingestion of Mycobacterium avium subsp. paratuberculosis (MAP) by host cells are fibronectin (FN) dependent. In several species of mycobacteria, a specific family of proteins allows the attachment and internalization of these bacteria by epithelial cells through interaction with FN. Thus, the identification of adhesion molecules is essential to understand the pathogenesis of MAP...

Cover image: A three-dimensional representation of the interaction universe of biological macromolecules and low molecular weight compounds. Each red sphere represents a chemical sub-space of macromolecules and each gray sphere corresponds to a chemical sub-space of ligands. Lines indicate multiple macromolecule-ligand interactions. Proteochemometric models describe interaction universe mathema...

Microtubule-associated protein 2 (MAP-2) isoforms are developmentally expressed in the nervous system and contain a number of functional domains. Adjacent to the first repeat of the microtubule-binding domain is an RTPPKSP motif for binding SH3 domains. To identify SH3-containing proteins that interact with MAP-2, transfections, filter overlay assays, glutathione S-transferase (GST)-mediated bi...

A map of protein-protein interactions provides valuable insight into the cellular function and machinery of a proteome. By measuring the similarity between two Gene Ontology (GO) terms with a relative specificity semantic relation, here, we proposed a new method of reconstructing a yeast protein-protein interaction map that is solely based on the GO annotations. The method was validated using h...

A functional analysis of protein fold interaction suggested that structural fold families have gradually acquired more diverse interacting partners while maintaining central biochemical interactions and functions. This means that the protein interaction network (map) maintains its robust architecture due to the functional constraints associated with the interactions.
