SH2 domain
Protein domain / From Wikipedia, the free encyclopedia
The SH2 (Src Homology 2) domain is a structurally conserved protein domain contained within the Src oncoprotein[2] and in many other intracellular signal-transducing proteins.[3] SH2 domains bind to phosphorylated tyrosine residues on other proteins, modifying the function or activity of the SH2-containing protein. The SH2 domain may be considered the prototypical modular protein-protein interaction domain, allowing the transmission of signals controlling a variety of cellular functions.[4] SH2 domains are especially common in adaptor proteins that aid in the signal transduction of receptor tyrosine kinase pathways.[5]
