Quantifying domain–peptide interactions in high throughput using protein domain microarrays. (a) A set of n protein interaction domains are cloned, expressed, purified and arrayed. The microarrays of protein domains are then probed with m fluorescently labeled peptides to reveal the full n × m matrix of domain–peptide interactions. (b) For high-affinity interactions (KD < 2 μM), dissociation constants can be determined directly using protein microarrays. Microarrays of protein domains are probed with eight concentrations of each peptide and the resulting saturation binding curves are used to determine the binding affinity of each domain–peptide interaction. (c) For low-affinity interactions (KD < 50 μM), microarrays of protein domains are probed with fluorescently labeled peptides and a fluorescence threshold is used to divide domain–peptide pairs into putative interactions (array positives) and putative noninteractions (array negatives). A secondary assay (FP) is then used to retest and quantify all array positives. The result is a quantitative interaction data set (data set 1) in which all the false positives in the <t>microarray</t> data set have been eliminated. To remove false negatives, it is necessary to build a model that can predict domain–peptide interactions. The model is then used to highlight suspected false negatives in the microarray data set, which are retested by FP. By performing multiple cycles of prediction, retesting and retraining of the model, many of the microarray false negatives can be corrected. This results in a substantially refined data set (data set 2).
