Functional protein-protein interactions are crucial in most cellular processes. They enable multi-protein complexes to assemble and to remain stable, and they allow signal transduction in various pathways. Functional interactions between proteins result in ...
Bacteriophages of the myoviridae family, R-type pyocin, Photorhabus virulence cassette (PVC), Serratia antifeeding prophage (Afp) and type 6 secretion system (T6SS) form a class of contractile injection systems that share common structural and functional c ...
Targeted cancer therapy is a very promising concept; however, small molecule inhibitors only exist for a limited number of oncoproteins and resistance development limits their clinical use. Different engineered non-antibody scaffolds are being explored to ...
In order to adjust to changes in the environment, cells can communicate via signalling cascades. A common pathway for intercellular communication is the G-protein-coupled- receptor (GPCR) signal transduction cascade which is triggered by a (chemical or phy ...
Contactin-4 (CNTN4) is a complex cell adhesion molecule (CAM) localized at neuronal membranes, playing a key role in maintaining the mechanical integrity and signaling properties of the synapse. CNTN4 consists of six immunoglobulin C2 type (IgC2) domains a ...
The binding of Src-homology 2 (SH2) domains to phosphotyrosine (pY) sites is critical for the autoinhibition and substrate recognition of the eight Src family kinases (SFKs). The high sequence conservation of the 120 human SH2 domains poses a significant c ...
Genetic disorders known as ciliopathies develop polycystic kidneys, including autosomal
dominant and autosomal recessive polycystic kidney diseases (ADPKD and ARPKD). Several signaling pathways including the cAMP/PKA pathway are implicated in driving cyst ...
Gyrl-like proteins are widely distributed in prokaryotes and eukaryotes, and recognized as small-molecule binding proteins. Here, we identify a subfamily of these proteins as cyclo-propanoid cyclopropyl hydrolases (CCHs) that can catalyze the hydrolysis of ...
Direct coupling analysis (DCA) is a powerful statistical inference tool used to study protein evolution. It was introduced to predict protein folds and protein-protein interactions, and has also been applied to the prediction of entire interactomes. Here, ...
Recent advances in DNA sequencing technologies led to the accumulation of enormous quantities of genetic information available in public databases. This rapid growth of available biological datasets calls for quantitative analysis tools and concomitantly o ...
