Interfacial water molecules in SH3 interactions: a revised paradigm for polyproline recognition.
In spite of its biomedical relevance, polyproline recognition is still not fully understood. The disagreement between the current description of SH3 (Src homology 3) complexes and their thermodynamic behaviour calls for a revision of the SH3-binding paradigm. Recently, Abl-SH3 was demonstrated to recognize its ligands by a dual binding mechanism involving a robust network of water-mediated hydr...
متن کاملCharacterization of domain-peptide interaction interface: prediction of SH3 domain-mediated protein-protein interaction network in yeast by generic structure-based models.
Determination of the binding specificity of SH3 domain, a peptide recognition module (PRM), is important to understand their biological functions and reconstruct the SH3-mediated protein-protein interaction network. In the present study, the SH3-peptide interactions for both class I and II SH3 domains were characterized by the intermolecular residue-residue interaction network. We developed gen...
متن کاملThe SH3 domain--a family of versatile peptide- and protein-recognition module.
Src homology 3 (SH3) domains were initially characterized as a prevalent protein module that recognizes proline-rich sequences, in particular those containing a PxxP motif. Recent studies have shown that the specificity and cellular function of SH3 domains are far more diverse than previously appreciated. Despite lacking distinguishing features, the ligand-binding surface of an SH3 domain can b...
متن کاملBinding of the proline-rich segment of myelin basic protein to SH3 domains: spectroscopic, microarray, and modeling studies of ligand conformation and effects of posttranslational modifications.
Myelin basic protein (MBP) is a multifunctional protein involved in maintaining the stability and integrity of the myelin sheath by a variety of interactions with membranes and with cytoskeletal and other proteins. A central segment of MBP is highly conserved in mammals and consists of a membrane surface-associated amphipathic alpha-helix, immediately followed by a proline-rich segment that we ...
متن کاملPredicting protein-peptide interactions via a network-based motif sampler
MOTIVATION Many protein-protein interactions are mediated by peptide recognition modules (PRMs), compact domains that bind to short peptides, and play a critical role in a wide array of biological processes. Recent experimental protein interaction data provide us with an opportunity to examine whether we may explain, or even predict their interactions by computational sequence analysis. Such a ...
