Evolution of SH2 domains and phosphotyrosine signalling networks

Published on Aug 17, 2012

This paper discusses the mechanisms by which cellular signalling networks (specifically phosphotyrosine signaling) evolve through the development of novel and expanded families of modular domain proteins and the elaboration of connections between nodes. These changes underlie the variety of general and specific signalling networks that give rise to tissue-specific functions and increasingly complex developmental programs.

This paper was also the focus of the cover art which imagines the evolution of SH2 domain proteins as a tree watered by phosphotyrosine residues created by kinase action.
