High-content functional protein microarrays, such as ProtoArray Human Protein Array from Life Technologies, contain thousands of proteins or protein fragments of biological significance. Based on this platform, numerous assays have been developed to investigate protein-protein interactions, protein-DNA interactions, protein-phospholipid interactions, small-molecule targets, substrates of protein kinases, substrates of ubiquitin E3 ligases, and substrates of methyltransferase. This article provides a detailed illustration of the general procedure for setting up functional assays for high-throughput screening and also provides guidelines for data analysis. The protocols include the use of fluorescently labeled and radioactive probes for detection. Curr. Protoc. Chem. Biol. 4:211-231 © 2012 by John Wiley & Sons, Inc.
