WebTyrosine phosphorylation by PTKs creates binding sites for SH2 domains that specifically recognize the phosphotyrosine moiety. Therefore, proteins containing SH2 domains can be recruited to the site of phosphorylation and signaling complexes can be formed in a phosphotyrosine-dependent manner ( 1 , 2 ). WebMar 12, 1993 · A mouse phosphotyrosine phosphatase containing two Src homology 2 (SH2) domains, Syp, was identified. Syp bound to autophosphorylated epidermal growth factor (EGF) and platelet-derived growth factor (PDGF) receptors through its SH2 domains and was rapidly phosphorylated on tyrosine in PDGF- and EGF-stimulated cells.

The C2 Domain of PKCδ Is a Phosphotyrosine Binding Domain - Cell

SH2 is conserved by signalization of protein tyrosine kinase, which are binding on phosphotyrosine (pTyr). In the human proteome the class of pTyr-selective recognition domains is represented by SH2 domains. The N-terminal SH2 domains of cytoplasmic tyrosine kinase was at the beginning of evolution evolved with the occurrence of tyrosine phosphorylation. At the beginning it was supposed that, these domains serve as a substrate for their target kinase.
