  • PubMed Abstract: 

    SH2 domains are found in a variety of signal transduction proteins; they bind phosphotyrosine-containing sequences, allowing them to both recognize target molecules and regulate intramolecular kinase activity. Fyn is a member of the Src family of tyrosine kinases that are involved in signal transduction by association with a number of membrane receptors. The kinase activity of these signalling proteins is modulated by switching the binding mode of their SH2 and SH3 domains from intramolecular to intermolecular. The molecular basis of the signalling roles observed for different Src family members is still not well understood; although structures have been determined for the SH2 domains of other Src family molecules, this is the first structure of the Fyn SH2 domain.
