Using SAXS and molecular modeling, my interest is to decipher shape /association order of protein(s) and their complexes of value. Prime interests include bonsai version of actin assembly regulating protein- gelsolin, peptides which modulate shape/association changes in human CD4, next-gen versions of tissue plasminogen activators and peptide-based vaccines. Initial data from SAXS based understanding of solution shapes of some large order assemblies are to be further understood by Cryo-EM based tomography.
