Antibody arrays identify protein-protein interactions in chronic myeloid leukaemia

Multiprotein complex formation with p210(BCR-ABL1) is likely to play a major role in determining cellular abnormalities in chronic myeloid leukaemia (CML). Although many p210(BCR-ABL1) binding partners have been identified, it is likely that many have not. We evaluated the use of co-immunoprecipitation and antibody arrays and found that this approach is capable of identifying new p210(BCR-ABL1) binding partners, and may contribute to the search for new therapeutic targets in CML.
