Descrizione Fibronectin (FN) is a high-molecular weight (~500-~600 kDa) glycoprotein of the extracellular matrix that binds to membrane-spanning receptor proteins called integrins. Fragments of this large protein have been crystallized and these structures are available from the Protein Data Bank (PDB). The student will attempt to create a computational model of the entire protein by using homology modeling of the uncrystallized fragments of FN and splicing together with the crystallized domain. This will be followed by equilibration using molecular dynamics. The ultimate objective is to find the binding modes of the known inhibitors of FN and, using chemical similarity searches, identify new small molecule inhibitors of the FN-integrin interaction. The PDB entry 7NWL will be the starting point for these searches. The final result will include the identification of a pharmacophore for the inhibition of the FN-integrin interaction.
