Description: Mutation and over-expression of Receptor Tyrosine Kinases (RTKs) or the proteins they regulate serve as oncogenic drivers in diverse cancers. RTKs catalyze the transfer of phosphate from ATP to the hydroxyl group on tyrosine. The proximal stretch of amino acids including this post translational modification is then able to be recognized by SH2 and PTB domains. Chapter 1 details our work to better understand RTK signaling and its link to oncogenesis using protein microarrays to systematically and quantitatively measure interactions between virtually every SH2 or PTB domain encoded in the human genome and all known sites of tyrosine phosphorylation on 40 out of the 53 Receptor Tyrosine Kinases.
Notes: Keywords: PTB, RTK, SH2, Tyrosine Kinase.
