Biophysical and Biochemical characterization of proteins which recognize, interact with, and modulate other protein molecules is the focal point of the work done in our laboratory. Diverse biological phenomena-the regulation of enzymes by polypeptide activators and inhibitors, the intracellular partitioning of enzymes between soluble and particulate structures, and the reversible phosphorylation-dephosphorylation catalyzed by protein kinases and phosphoprotein phosphatases-entail specific protein-protein nteractions.
Specific areas of investigation include: (1) characterization of specific complexes formed by the Ca2+ binding protein calmodulin with biologically active peptides and enzyme-derived fragments; (2) investigation of the significance of the phosphorylation sites of muscle phosphofructokinase; and the role of Ca2+ binding proteins in the phosphorylation reaction; (3) characterization of oxidative modifications of calmodulin; (4) development and application of fluorometric assays for protein kinases and phosphoprotein phosphatases.
