Mitogen-activated protein kinases (MAPKs) are key components of cellular signal transduction. It is the objective of this communication to demonstrate that insight into protein-protein interactions in the Common Docking motif of yeast mitogen-activated protein kinases can be obtained based on homology models. Homology models for four yeast MAPKs, FUS3, KSS1, HOG1 and MPK1 were built based on the X-ray structures of active and inactive rat ERK2. The structural motifs required for the basis of specificity were rationalized based on these structures.

Keywords: Homology; common docking motif; mitogen-activated protein kinase; molecular modeling; signal transduction; yeast

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
