Protein Phosphatase Protocols presents a broad range of protocols for the study of protein phosphatases, all written by experts and innovators from phosphatase laboratories around the world. This volume is a compendium of resources for the study of protein phosphatases and their potential as drug targets. Experimental methodologies are taken from proteomics, bioinformatics, genomics, biochemistry, RNAi, and genetics. Included protocols utilize several model organisms, including yeast, Drosophila, and various plant and human cells. Protein Phosphatase Protocols provides a concise introduction to protein phosphatase research, with particular attention to phosphatase families. Assays for identification, quantification, purification, and functional characterization are presented throughout in specific detail.
