Phosphotyrosine signaling: evolving a new cellular communication system

Cell. 2010 Sep 3;142(5):661-7. doi: 10.1016/j.cell.2010.08.023.

Abstract

Tyrosine phosphorylation controls many cellular functions. Yet the three-part toolkit that regulates phosphotyrosine signaling-tyrosine kinases, phosphotyrosine phosphatases, and Src Homology 2 (SH2) domains-is a relatively new innovation. Genomic analyses reveal how this revolutionary signaling system may have originated and why it rapidly became critical to metazoans.
