英文摘要
Project Summary
Antibodies can facilitate the study of associations between different proteins in the cell using a
technique known as immunoprecipitation (IP). This approach can reveal differences in protein
associations present in healthy vs. diseased tissues, provide targets for diagnostics and
therapeutics, and reveal protein--protein interfaces that could be druggable targets. It is widely
recognized that a lack of high quality antibodies against human proteins is negatively impacting
biomedical science. CDI Laboratories, Inc., has developed a pipeline that employs the largest
content full--length human protein array to generate quantifiably monospecific mouse
monoclonal antibodies (mAbs), and has generated a large number of mAbs against human
transcription factors (TFs). The PI of this project has developed methods that enable and
optimize the capture of endogenous protein complexes by IP in conjunction with mass
spectrometry analysis. In Phase I of this STTR project, Aim 1 will characterize anti--human TF
mAbs for their ability to IP endogenous cancer--related TF protein complexes. This will be
accomplished initially using human tissue culture cell lines to establish quantitative functional
metrics of the mAbs, and then applied to protein complexes isolated from patient-‐derived
cancers. In Aim 2, cancer--related TFs will be used as bait for IP of native complexes, and novel
mAbs will be generated by immunization with the endogenous TF protein complexes. The
target specificity of the mAbs will be determined using the human proteome array, yielding a
catalog of new, high quality mAbs with which to study protein-‐protein interactions within
cancer cells. The long term goal of the project, which will be expanded and achieved in Phase II,
is the production of larger numbers of high quality mAbs against native human proteins that are
normally found as constituents of complexes in healthy and cancerous cells.
