Our protein-domain microarray technology facilitates the identification of proteins that interact with motifs that carry phosphorylation, methylation and acetylation modifications. This high-throughput approach allows for the rapid identification of protein-protein interactions in vitro. Additional experiments are then required to confirm that these interactions do indeed occur in vivo and in vitro.
We have developed a chip-size array of proteins that can be used to identify the “readers” of specific PTMs. We are the only research group to have such a large collection of protein domains. Thus, many researchers, who have identified PTMs that are often unique signatures of a certain cancer, send us their modified proteins in the hopes that we can identify relevant binding partners. We are now expanding this facility to not only include state-of-the-art protein domain microarrays, but also to allow the further characterization of these protein-protein interactions in cells. In addition, we will provide the instrumentation and know-how to determine the strength of these protein-protein interactions.
The following table provides a guide for requirements for various kinds of experiments, the sample requirements of the Core, and estimated costs. For more detailed information, please call or e-mail to set up a meeting with Core staff. Contact Mark Bedford (mtbedford@mdanderson.org) for experiments involving the use of protein domain microarrays and surface plasmon resonance (SPR), and contact Shawn Bratton (sbbratton@mdanderson.org) for experiments involving the biophysical analysis of protein complexes.
