Comprehensive binary interaction mapping of SH2 domains via fluorescence polarization reveals novel functional diversification of ErbB receptors.

Hause RJ, Leung KK, Barkinge JL, Ciaccio MF, Chuu CP, Jones RB

First-generation interaction maps of Src homology 2 (SH2) domains with receptor tyrosine kinase (RTK) phosphosites have previously been generated using protein microarray (PM) technologies. Here, we developed a large-scale fluorescence polarization (FP) methodology that was able to characterize interactions between SH2 domains and ErbB receptor phosphosites with higher fidelity and sensitivity than was previously achieved with PMs. We used the ...

  • High Throughput

Additional Notes

  • interaction assayed using fluorescence polarization (FP) measurements using one or more phosphopeptides derived from the bait protein and all or a portion of the purified prey protein
  • note that a non-phosphorylated version of a peptide derived from the same bait protein was also found to interact with the same prey protein
  • this results in one or more KD values measured in micromolar (0.126666667,0.39,0.62,2.356666667,2.433333333,2.46,2.476666667,2.88,3.07,3.86,4.54,5.96,7.31,7.88,11.155,11.91,14.16,18.16,18.91,18.96) of which the minimum value representing the highest affinity interaction is reported in the HTP score

PCA

A Protein-Fragment Complementation Assay (PCA) is a protein-protein interaction assay in which a bait protein is expressed as fusion to one of the either N- or C- terminal peptide fragments of a reporter protein and prey protein is expressed as fusion to the complementary N- or C- terminal fragment of the same reporter protein. Interaction of bait and prey proteins bring together complementary fragments, which can then fold into an active reporter, e.g. the split-ubiquitin assay.
